Description udo 2013-07-16 14:12:23 UTC

Hello,

See https://bugs.freedesktop.org/show_bug.cgi?id=62959 as reference.
I turned off RADEON_VA=0 and R600_DEBUG=nodma and after a while I got the output below (and a reboot) while surfing the web, checking videos from youtube, etc. I use git everything on A10-5800K which has ARUBA (Cayman) GPU with kernel.org 3.9.9.
What is the cause? And how can we fix this?

Are things improved any with Dave's drm-fixes tree:
http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-fixes
It contains some alignment fixes for VM that may help and it should provide better debugging output of the VM faults.
