Bug ID: 91667 Summary: Tonga Oopses with uvd + agd5f drm-next-4.3-wip Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: adf.lists@gmail.com

Created attachment 117730 --> https://bugs.freedesktop.org/attachment.cgi?id=117730&action=edit Oops 1

Tried the newly updated agd5f drm-next-4.3-wip today and got some oopses with uvd.

These are provoked by repeatedly starting a vid with mpplayer - a known issue, but the change for me on Tonga is getting the Oopses.

On other kernels amdgpu/amd-staging/drm-fixes the same test would provoke a ring 9 lock (rarely ring 0) and a failed reset, which at least would leave me alive enough to get a VT.

I notice GPU stall detection has now been disabled - but testing various 4.3-wips over some weeks I have never got one anyway. Doing something like this test or running valley would just lock the display and log nothing. SysRq worked OK as it still does - just now I get some logging (though not for the one Unigine Valley lock I just provoked).

I am now running mesa/drm mesa/mesa Git Xorg with DRI3 enabled.

While testing I noticed the tree got another update - retested and still get the same.

The first 2 are from the older tree, the second long as secondary Oopses were provoked.

The third is current.
