Bug ID: 88301 Summary: Dota causes GPU fault and kernel hang Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: tilman@code-monkey.de
I've got an apitrace of Dota that reliably causes GPU faults on radeonsi on my Bonaire XTX.
The trace: http://files.code-monkey.de/dota.trace (468797931 bytes).
I'm running Mesa from master (8d2542fc9d5af4db355b67cc2a1ff2f413685a27) and can reproduce the problem with kernel 3.18.2 and 3.19.0-rc2 (built from airlied's drm-fixes tree; 79305ec6e60d320832505e95c1a028d309fcd2b6). agd5f's "fix VM flush" patches from 2015-01-06 don't help either.
