Priority: medium Bug ID: 60347 Assignee: dri-devel@lists.freedesktop.org Summary: Reproducible GPU lockup CP stall in Amnesia game Severity: normal Classification: Unclassified OS: Linux (All) Reporter: anonymous@dodgeit.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

There is/are a reproducible GPU lockup in Amnesia: Dark Descent video game on Linux x86-64. Often it occurs when looking at certain doors in the levels. I find that using VT-switch helps to recover the GPU in a reasonable timeframe to a somewhat usable state. I do experience some jerkiness though after the stall recovery.

Radeon 6750M

3.8.0-rc5 Everything else taken from xorg-edgers ppa

I'm happy to investigate this issue further.
