Priority: medium Bug ID: 62997 Assignee: dri-devel@lists.freedesktop.org Summary: GPU fault unless R600_DEBUG=nodma Severity: major Classification: Unclassified OS: Linux (All) Reporter: udovdh@xs4all.nl Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

Ever since booting into kernel.org 3.8.4 on my AMD A10-5800K (ARUBA graphics), running git mesa and git xf86-video-ati, I get short uptimes (15 minutes, around one hour max) due to crashes. The logs mention stuff like:

[ 1332.480233] radeon 0000:00:01.0: GPU fault detected: 146 0x0134710c [ 1332.480243] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000813 [ 1332.480250] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0407100C

Watching youtube `helps` triggering the issue as it appears. (correlates, no real causation yet) Having R600_DEBUG=nodma in the environment solves the problem.

Occasionally I see a GPU lockup, if that is related:
