It would probably be better to initialize job->vm_pd_addr with
AMDGPU_BO_INVALID_OFFSET.
And then just drop the vm flush alltogether when the vm_pd_addr isn't
set to something sane.
Thanks,

Attached patch fixes SDMA TO after GPU reset, it's a regression caused
by cbd5285 drm/amdgpu: move setting the GART addr into TTM.
But to me it looks safer just to revert the original patch all
together since we never can predict for sure if VM flush will take
place and so it's safer to just always assign job->vm_pd_addr.
