This smells like the same issue that Andres Freund reported:
https://lore.kernel.org/all/20220814043906.xkmhmnp23bqjzz4s@awork3.anarazel.de/
he blamed the virtio changes, mainly based on the upstream merges
between his bad tree and last good tree, ie
git log --merges --author=torvalds --oneline 7ebfc85e2cd7..69dac8e431af
and assuming those end-points are accurate, that does seem to be the
most likely area.
Andres was going to try to bisect it, but if you have some idea where
this all started, that would help.
