[Atrix 4G Android Development] sendust7:
Well those random reboots are definitely surfacing as I push That ROM's buttons. So I decided to embark on some research, mainly asking the question: Could the radio be in the fault loop, and if so, is it really the radio or perhaps some bloatware/spyware?

Here is my listing of That ROM's APKs under /system/app (about 150 in all):

Then I tried an experiment by removing some bloatware and a few apps with suspicious names: Here's the removal list:

DataCollection.apk
DeepSleepService.apk
EncryptionSettings.apk
FastDormancy.apk
ModemCutback.apk
ModemPanicReporter.apk
SmartActionFW.apk
SmartActionMFW.apk
SmartActions.apk
SuggestionsProvider.apk
SuggestionsRuleCheckerCore.apk
SuggestionsServiceScheduler.apk

Then I rebooted to CWM, created a system.img from my system partition, recreated my SD card's /system, /cache and /data partitions (I'm hosting That ROM on SD), pushed system.img to system partition, rebooted and... well, all I can say is that in the past 90 minutes I have not experienced a single random reboot, and my phone runs much cooler (Battery Tracer v3.7 shows battery at 25C and CPU at ~45C steady state with the display on at moderate brightness. I even ran a fiber optic screensaver under Ubuntu 12.04 (hosted on EMMC) and CPU temp remained stable.

My next step, after some more burn-in time, is to gradually reintroduce certain apps and watch the behavior.

I do know that Fast Dormancy is able to do good or evil depending on whether the network supports it, lol.
