Kernel Version: 3.17
Hardware: x86-64
OS: Linux
Tree: Mainline

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).
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:

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=57d20a43c9b30663bdbacde8294a902edef35a84

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.
