[Nook HD, HD+ Android Development] :
Alright... going back to logs. All my testing seems to be missing the actual problem with the reboots.

Have noticed two (looks like more now) differences in logs since the last time parts were pasted.

[ 9935.427124] Kernel panic - not syncing: Attempted to kill the idle task!

This appeared on early 10.1 nighty builds. Before that is was: Kernel panic - not syncing: Fatal exception. My only (my bad) 10.2 log (8/24 nightly) also shows fatal exception. I am assuming this is of importance.

[18953.529174] Unable to handle kernel paging request at virtual address 1c1e6852

[18953.530334] LR is at HASH_Retrieve_Extended+0x28/0xb0 [pvrsrvkm_sgx544_112]

This is from the 10.2 log (8/24 nightly). This is the only log showing kernel is tainted by G and C ? (or that is how I understand it).

Towards the end of my 10.1 logs this is what occurred:

[40416.561370] Alignment trap: not handling instruction e1920f9f at [<c0092864>]

[40416.561492] Unhandled fault: alignment exception (0x001) at 0xeb0237b2

[40416.562713] LR is at __schedule+0x254/0x63c

Before the logs showed Kernel isn't tainted. Also these errors look interesting.

It is possible various tests have influenced what's in the logs. Hope this actually helps?

EDIT: Reboot hit right after posting. This one is odd to me. Not like any other. Zram is disabled while this one occurred (This kill stuff can be seen just before the unable to handle kernel paging, internel error, pc, lr section found in all others). As you can see there are no normal errors - its short and doesn't have much (there is more before this but appears just normal stuff to me) (also had updated to 8/26 nightly after last reboot, so this is from 8/26 reboot):

Because the logs are getting more interesting, I will zip and post them as soon as I can. Don't know when exactly.
