Hey Andrey,
this is on Vega10, so the ASIC always stops after it sees the first fault.
I'm actually working on implementing that it should continue without
interruption.

Christian.

Looks like you are still running this without the latest hang fix
since i see the deadlock again, but actually what i forgot to ask you
is to load amdgpu with vm_fault_stop=2 to freeze the ASIC once
VM_FAULT is encountered - sorry about that. So please retest with
amdgpu.vm_fault_stop=2 parameter in GRUB loader.
