Sure, that would be common wisdom. However the commit before anything
related to driver was added for 5.18 is also bad. It could be
pre-existing, but that starts to seem unlikely. Or it could still be an
IOMMU issue - we already have a performance issue there.
This issue can take more than 15 minutes to occur, so is pretty painful
to bisect...
Thanks,
John
