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.
Regards,
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.

Just in case,
I duplicated all the files on the file sharing
