Alright guys, so I did some extra searching and digging, and I've found that this random reboot issue is a widespread issue across ALL CM12 builds on all devices! [MENTION=4817632]varund7726[/MENTION] I'm not sure how this relates to what you said about the RIL blobs, but I think you should read the info I've dug up below in case you haven't seen anything about it yet, as users are reporting this issue on different devices all over the CyanogenMod forums, so the reboots may not be entirely due to the Sirius RIL blobs.

One moderator on those forums has replied to most of the threads saying, "The leading theory on the random reboots currently deals with the CVE patches that have been put into the builds to fix the stagefright issue among other things. The issue is that while the builds are patched and updated, 3rd party apps may not be. These apps will hit up against the CVE change continuously, which will cause an out of memory error and cause the reboot. Two examples of apps that we have seen that have caused this are greenify and lastpass. However it could be any app that is not patched. The only way to tell which app could be causing it is to do a clean wipe of the device then slowly add apps back until you see the reboot. " And he clarifies, "This can be ANY app that uses the processes that have been patched."

Add facebook Messenger to that list of apps because I had three reboots in a row, yesterday that happened immediately after the Messenger's 'ding' notification sound played.

I'm not really sure how this theory ties in with the reboots some of us have had that seemed to be caused by connecting to WiFi, toggling mobile data, and the SIM card errors (maybe it's a combination of both the stagefright patch issue and the RIL blobs like varund said or maybe it's apps grabbing data as soon as WiFi or data connects and then hitting the CVE change issue), but the theory does seem to fit with when these reboots started happening, as I first noticed them on RR 5.5.4 and that was the first build with stagefright mentioned in the changelog. Although, apparently CM started adding CVE patches as far back as "a few weeks" before July 27th according to this Google+ post by Cyanogenmod, I think it may not have been causing an issue until newer patches were introduced around the end of August, but I could be wrong about this. I'm basing my timeframe assumption on when I personally started noticing random reboots on RR and when all the threads on the CM forums are dated (earliest were from the end of August).

I'm surprised there isn't more commotion online considering this is affecting all devices with CM, but it seems like the only thing for us users to do is either wait until all the app devs out there update their apps or CM team fixes their patches to be compatible with non-updated apps, or we can revert to a rom build from before the stagefright patches. I'm going to be doing the latter and clean install RR 5.5.3.

I hope this info helps everyone else out. I'm tagging everyone I've seen report this issue so you all can be informed as well...

Did you happen to uninstall any apps or change anything that you think may tie into the theory I've mentioned? Just curious.
