After upgrading mesa from mesa-10.3.0 to mesa-10.3.1 the Radeon HD 7700 card locks up several times a day without any specific trigger (or reliable way to reproduce it). Xorg appears frozen with just the mouse pointer moving. It's not even possible to switch to a VT, however everything else works just fine. At any given time the X bt looks like this: Thread 2 (Thread 0x7fe8147be700 (LWP 2415)): #0 0x00007fe81b4d911c in pthread_cond_wait () from /lib64/libpthread.so.0 #1 0x00007fe816a807a3 in ??

Created attachment 156761 [details] lockup example (no oops)
After upgrading mesa from mesa-10.3.0 to mesa-10.3.1 the Radeon HD 7700 card locks up several times a day without any specific trigger (or reliable way to reproduce it).
This sounds like a mesa regression rather than a kernel driver bug. Can you bisect mesa?

I understand mesa may be sending crap to the kernel space but that doesn't sound like a good reason to deref a NULL.
As for bisecting mesa, I am certainly willing to do that but I need a reliable way to trigger the lockup rather than just log in and wait for it to occour. Will see if I get more hints over then next few days.

AFAICT that should be fixed by the changes to radeon_ttm.c in https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5... .

--- Comment #5 from aCaB acab@digitalfuture.it --- Michel, Thanks for your pointer and sorry for the late answer.
I'll try harder to find a reproducible case (firefox with some large animation seems to trigger it some times). In the meantime, if the lockup is a mesa bug then feel free to close this ticket.
