Partial kernel log showing many GPU faults and subsequent page table breakage
I'm reliably able to trigger GPU faults and various subsequent problems. The
crash doesn't happen immediately, so far as I can tell.
One known trigger is to start a map then start another map on Unvanquished
(http://www.unvanquished.net/). It appears that the heat haze option needs to
be enabled (this one seems most reliable), and I think that the motion blur
option may also trigger this.
Known effects, other than reams of GPU fault reports, include hard lock-ups and
page table corruption; the attached file (gpu-crash-etc.txt) shows the latter
(I chose to reboot soon afterwards).
Hardware is Bonaire XTX. Userland is X git (2535b76) with corresponding Radeon
DDX, Mesa 10.2 git (e05ceba, built using xorg-edgers packaging), llvm 3.4-2
(Debian). GLAMOR is enabled.
