Kernel log of lockup
Using Kubuntu vivid with linux kernel 4.2-rc7 (from ubuntu mainline repo), and
mesa/xorg from the oibaf ppa with a self-compiled xf86-video-amdgpu driver I've
been getting random GPU lockups. When the lockup happens the computer seems to
get stuck for a few seconds, then I get a black screen and a few seconds later
the screen reappears, and I am able to move the mouse, but can't click
anything. If I go to a tty and restart X it seems to resort to using llvmpipe,
instead of amdgpu, and that works fine (without any acceleration).
If it's relevant, I am using a multi-monitor setup.
I have attached a kernel log of the lockup, and it looks to me like what's
causing the lockup is this:
[ 2481.663794] amdgpu 0000:01:00.0: ring 9 stalled for more than 10000msec
[ 2481.663798] amdgpu 0000:01:00.0: GPU lockup (waiting for 0x0000000000013658
last fence id 0x0000000000013657 on ring 9)
[ 2481.663804] amdgpu 0000:01:00.0: failed to sync rings (-35)</pre>
