Hi Mikhail,

well short answer is not at all :)

After the GPU reset happened all waves should be gone and the gfx block 
in a clean state again.

What you need to do is to disable automatic reset by setting 
amdgpu.lockup_timeout=-1 on the kernel command line and then inspect the 
system over ssh.

Regards,
Christian.
