Would you mind to enable this and try it again? The recent gpu reset testing on
vega20 looks very positive.

Mhm intentionally ignored those errors because the compute rings sometimes
doesn't come up again after a GPU reset.
We even have the necessary logic in the SW scheduler to redirect the jobs to
another compute ring when one fails to come up again.
