I have decided to start new thread for all who suffer from random soft-reboots while using CAF based ROMs.
There are two reasons for that:
1. I don't want to spam single ROM threads since it seems to be a general issue of CAF ROMs (mainly for D802 users)
2. I want to gather all knowledge in one place and figure out a root cause and solution (or workaround).
I was trying several CAF based ROMs and I'm delighted by their responsiveness. But unfortunately I'm suffering from random reboots. I'm not able to get to root cause of this issue. Initially I thought this is because of some app, or by failure while flashing ROM. Issue is hard to diagnose since phone may be fully-functional even for couple of days. That is why for several times I thought the issue is gone....
Now I am heading more towards modem issue - weak signal and changing BTSes. When I'm on countryside, my phone is able survive couple of days without a single reboot. When I move back to the city (and move around for a while) reboots are becoming more frequent, especially when I'm in the areas with weak signal. I have even got some "favorite" places, when possibility of getting soft-reboot is higher than usual.
Please describe your observations of this issue, providing:
Phone variant: D802
ROM: SlimSaber 0.4
Kernel: provided with ROM
Bootstack: Drgravy's loki LP bootstack from here
Modem (baseband): provided with bootstack (M8974A-AAAANAZM-1.0.190128)
Logs with approximated crash time: I'll deliver mine when I'll catch first soft-reboot after hard reset. If you're not sure how to get logs from crash, please use this app.
Observations:
1. Reboots get more frequent when changing location, visiting areas with lower signal.
Suggested solutions/workarounds:
1. Change modem - DOESN'T WORK FOR ME
Tested on the following modems:
- included in Drgravy's LP bootstack
- cust 30A SG by samuele94(Lg g2 Original Modding Italy G+ Community)
- Modem_D802-30B_EUROPE-OPEN
2. Play with Location/APN settings - PARTIALLY WORKING
Please refer to this post.
After couple days of testing with Location set to Device only I have face one or two reboots. Acceptable for me. Probably switching to Battery savings will remove reboots completely (as reported by others)
3. Disable MPDecision hotplug - DOESN'T WORK FOR ME
Doesn't work and for some kernels inhibits deep sleep.
4. Try to flash kernel from this post: WAITING FOR REPORTS

I work as a truckdriver and move around a lot. I can confirm that my phone is more stable when I am stationary than driving around. There is a lot of RIL errors in my logs.
I have been speculating to myself that it might have something to do with switching networks from wi-fi to cellular or the other direction. I ride the train to and from work, and the local cable company has free wi-fi at most of the train stations. So as we approach and leave each of the stations, my phone joins and leaves the wi-fi. I started to notice that the phone, just sitting on my lap asleep without me touching it, would suddenly turn on showing the boot animation. It would do this two or three times in a 45-minute trip. I also have the "avoid weak wi-fi" setting turned on, and the other times I've noticed the reboot have been when I'm in a weak signal area (either wi-fi or cellular, like the back of a store).
I got the soft reboots on tsunamical's Euphoria 6/10 build (I never updated to the later ones because people were still reporting the soft reboots). I switched to dr87's Euphoria build this past weekend to see if it was any better, but I was getting them there too. Which at least suggests it's not a kernel problem, maybe, since that's the main difference between them? Anyway, I was just about to start collecting logs and then...
All of a sudden, yesterday morning on the train was the last soft reboot. It didn't reboot once on the train ride home, or the train ride in this morning. Oddly, CPU Spy thinks the phone has been up for about 9 hours LESS than GSAM Battery Monitor does (usually both would only show time since the last soft reboot). So SOMETHING changed around 4pm US Eastern time yesterday, but I'm not sure what. I thought it might have been Google Play services, but that seems to have not been updated since June 18th. But, a few days ago, Google Play services had hundreds of wakelocks. Now? It has 7. Just 7.
I have no idea what all this means, but offer it for what it's worth (or not worth).

Haven't we already confirmed it was an issue with the modem panicking?

I'm sorry if that topic was already covered. I (and, looking through several threads, bunch of oher users) was not able to find that conclusion.
My intention was to move the discussion scattered all over the development threads into one place. I think users without reboot issue have already enough reading about it
I have this issue after installing build 2015-07-02 BlissPop v3.6 by electrikjesus.
Before this I had reboots whrn data changes from wifi to LTE or the reverse way. But now the reboots are random.

Being on Euphoria I don't get any issues like that. Model D802 plus loki lp bootstack. Perhaps bootstack is the issue? I tried others ROM too and have never experienced any reboots. Om Euphoria just several lags possibly having something to do with thermal throttling when phone being heavily used.

Thanks for this thread.
802, BlissRom (just flashed today's build clean)
Loki bump bootstack.
Mine will reboot on:
Phone call (random times, sometimes 1 min in, sometimes 10mins in)
Almost always when at station (very low signal) AND when starting music through headphones (uninstalled native music player and using Google Play music now, testing)
Sync BT with car, play music, reboot (only once out of 5-6 times, rebooted half way through song) - was driving out of underground carpark so no signal
about 50% of the time, it will reboot and then 'optimize apps', it's like an auto wipe dalvik cache!! (which is crap since if you want to phone back the person, you have to wait 15-20mins while apps optimize....)
Played music through headphones at home for hours, no reboots. So definitely related to signal/modem etc.
Will post more when testing done this week
Well I need a kmsg after a reboot (pull it from twrp) a modem log please
Edit I don't have any random reboot (bliss d802)

Thanks genesixxbf3
Attached Syslog bunch of files - not sure how useful this is as the phone dalvik wiped, then launcher loaded, then 30 seconds later rebooted itself. Only then could I run syslog
The catlog dump was recording when I was on the way home yesterday, and phone rebooted (was on train so likely to be switching towers). Had headphones in and playing music.
I'll do the TWRP log when it reboots tmr.

You will find that in my post. The second in this thread.
Solution?
Yesterday I did something no tester should do in life - changed two settings at once
I have:
changed Location settings to Device only - thanks to LooseSeal
changed APN settings - I don't know why, but I have changed APN (from the one I was using for years to my provider's secondary APN).
As a result:
my phone works for 19 hours without a single reboot. Usually I should have at least two of them - way back from work in the afternoon and to work in the morning. Not mentioning several at my home - I have, by purpose, put the phone in "low signal area location" of my flat where usually reboots are frequent. :good:
when leaving WiFi area my phone connects to LTE network much faster than before. :good:
If my phone continue to run reboot-free, I'll change back Location setting to High accuracy and report after a day or two.
Update:
After 21 hours of testing (no single reboot during that time) I have changed Location settings back to High accuracy to verify if APN change is enough to get rid of reboots.
After 27 hours of testing still nothing. Now the real test - trip home from work.
Unfortunately - three soft-reboots with High accuracy. Changed back to Device only and restarted.
After couple days of testing I've got two soft-reboots - maybe not related but they occurred one after another while watching something on YouTube. For me phone is stable enough for now. Moreover, probably after following suggestion of LooseSeal - reboots will stop completely after changing Location settings to Battery Save
Phone did not reboot at station today. Played music, surfed web etc... lol... hmm...
Did you change anything?
Flashed latest BlissROM yesterday.
The Banks GAPPS didn't install Play store (weird) so I got the APK and also the latest Google Services and installed those manually. All my apps are the same (Titanium restored)... test again tmr see if it doesn't reboot
My solutions for D802 (but only theoretical because I don't have any reboots - currently 4 days uptime in CM 12.1 ROM) :
Try Nice & Fruity 0.25 CAF Kernel (or latest version e.g. 0.30) with patched panic handler (I will build in next week another version with more possible fixes)
Nice & Fruity 0.30-PAN!C CAF Kernel with patches from previous versions + disabled LG panic handler and watchdog v2
Flash KK modem (logcat will throw rild errors, but signal will work - it's a temp solution)
Remove/update Xposed
Please report back if something fixed those weird reboots
Best wishes !

Nice for the panic handler cause watchdog panic muck up my kernel

The only thing I had to do to completely stop reboots for a few days now was to set GPS to device only instead of high accuracy.
Haven't had one reboot and the battery life has basically been twice as good then before
Hello,previously i have installed the custom rom of CM12.1 by @TecnoTailsPlays and i was having the issues of play store & whenever i play an audio or video whether online/offline &while download the apps like ASPHALT 8 the whole mobile gets stuck & the screen freezes & i need to restart it by long pressing the power button.Also i cannot play videos for more than 10-15 minutes neither in built-in video player nor in MX player & after that the screen freezes.I thought this might be the problem with the custom rom so i decided to change the custom rom from CM12.1 to Recreated Remix Ultra v7.2 ("http://forum.xda-developers.com/zenfone-5/general/recreated-remix-rr-android-5-1-1-t3271397") and the problem is still there. So what will be the reason for this problem & the solution also.
Re-Unlock the bootloader manually
I have re-unlocked the bootloader manually & after the 5 min of restart I launched asphalt 8 & after 2-3 min the mobile got stuck again.
freezing while playing
i have the same problem too,,please help,,,,
i try kernel audiutor ,,,in playstore,,,
,,,open
and open cpu,,
then close core 3and 4,,
then try play games or any,,,
no freeze,,,,,,,
im not sure ,,its working on your phone,,
just tryy it,,app need root,,
,,
There's no way to fix freeze issue and use custom ROMs
Lock your bootloader and return to stock JB/KK or LP.
Hi. I have random reboot problem on my note 3. Screen freezes (gaming, settings, menu or idle) and reboots when i have installed ANY costom ROM or Kernel. I noticed screen freezes mostly when Synapse app is installed with Kernel, second notice phone freezes then my favourite PegasusQ governor is applied. Phone was working perfectly without any issue on official 5.0 with Minimalistic kernel, no issues about whole year (no synapse). Phone was two times in warranty. First time they instaled stock KK firmware and replaced micro usb port (that whole part in note3 ) ?? , second time simply installed stock Lollipop. And then everything starts from beggining...
Yesterday I zipped all LOGS with SysLog app when random reboot appeared (i was on synapse changing governor from interactive to precognition). If it helps reboot happened yesterday after 02:00 hour.
Zip here: https://www.dropbox.com/s/a3svst1yhhtj23u/2016-02-08_11.20.zip?dl=0
Warranty didn't fixed that so I hope real developers will detect what couses this RR.
Sorry for bad English
My phone is now on Phronesis ROM, CivZ_Xplorer-9005-Rev5.0.3-note5port Kernel
Do you have an SD card installed? If so remove it from the phone and see if the phone is stable
I was using external sdcard on official 5.0 lollipop with minimalistic kernel and phone was working without random reboots whole year.... Reboots only on costom roms and kernels with synapse.... I never used costom voltages and higer cpu freequency than 2.5 ghz... no gpu overclocks more than 450mhz, never played with performance governors, no overheating...
Reflash different stock firmware it worked for me

I searched around and couldn't find anyone with a similar issue.
I'm running the most recent Bliss build on my G900T Tmobile S5 using the stock kernel. I've tried (and love) Boeffla's klte kernel for CM13 on both Bliss and stock CM13 (as per his recommendation). On both builds, I encounter the same issues after flashing Boeffla kernel, and I was just wondering if anyone could offer some advice. Both test flashes are completely clean. I've tried flashing the kernel with and without gApps on both ROMs.
When I flash the kernel, I lose all of my pull-down toggles (Wifi, Bluetooth, location, etc), as well at the "gear" icon in the status bar. Additionally, no incoming notifications are displayed in the notification bar from any app, although the notification sound still fires off. I dug through the settings and the options to restore them have disappeared as well.
I also lose Bluetooth functionality and root. I tried to grab a log file to see what was happening, but the Bluetooth Share FC's would not let me do anything in the ROM after a few minutes of being powered on. Bluetooth will work fine for about 30 seconds, then start producing errors from the Bluetooth Share apk. Eventually the seetings toggle itself freezes and only restarting the phone "fixes" it. I tried re-installing root with many different apps (Chainfire's, SuperSU, etc), but to no avail.
For now, I'm back on Bliss with the stock kernel, running smoothly.
If anyone has any suggestions, please let me know! Boeffla Kernel is excellent, and I really miss intellidemand >.>
Thanks!
The Bluetooth issue is from the upstream cm13 code base it came about around 06/06 on the nightlies there are posts scattered throughout all of the builds based on cm13. So far haven't heard of a fix.

Hello guys, since today I'm experiencing a noticeable slowdown when I load almost any app. It takes 7-8 seconds to open Google Dialer for example.
I'm on stock 8.1 september + root + moun kernel, I tried everything (disable modules, reflash Magisk ec.) but the problem still persists. Androbench shows normal storage speed, so I can exclude an HW issue I think. What can I do?

I think it's the kernel you flashed, or maybe a programme you've recently installed. Also, when opening the app, does it stay on the home screen, or goes into the app immediately then waits for the app to launch? (If you know what I mean)
