Just your irregular GPU stops responding. The stop rings request prior
to the GPU reset also failed, so likely the CS parser was stuck or it
was exploring an infinite batch or an empty address space.

That it affected gem_sync makes me wonder what happened with the
duplicate patch I accidentally included. It didn't trigger on my pnv, so
just the usual irrational GPU that we wait and see what patterns
evolve.
