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.
