Comment 1 Jani Saarinen 2017-09-01 06:55:58 UTC 
Same issues seen on 102457. Dup?
Comment 2 Chris Wilson 2017-09-01 09:54:34 UTC 
Kind off. Except you will need to add a test that is run at the start of each shard to check that the GPU is usable (along the lines of gem_exec_store) as well as the kernel integrity is intact.

What you are looking at here is that the GPU died on its very first execution of the BSD (VCS) ring, which uses means a stale TLB.

Never seen again. Closing
