Bug ID: 85320 Summary: GPU hangs using hardware acceleration Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: ken20001@ukr.net
With new kernel 3.18RC1 trying hardware acceleraton I discovered GPU hangs. Running 'mpv -vo vdpau --hwdec vdpau filename' starts to play movie and all it seems ok. But if we try to rewind forward/backward first it, playing, hangs. Than all system hangs. Switching to another VT in dmesg appears:
[drm:r600_ib_test] *ERROR* radeon: fence wait failed (-35). [drm:radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on GFX ring (-35).
Switching back to VT7 we can watch that image appears and disappears. Restarting ligtdm service allowed me to log in to account. But anyway all system switched to XRender and no OpenGL until I fully reboot.
