Also after reset there is often a long wait, up to 2 minutes, for all the tlb_fence_work to timeout (not addressed by this patch, still haven't figure out what's going on there)

The problem is that we don't force complete the non scheduler rings, 
e.g. MES, KIQ etc...

Try to remove this check here from the loop in 
amdgpu_device_pre_asic_reset():

                 if (!amdgpu_ring_sched_ready(ring))
                         continue;

Regards,
Christian.
