Remember that with the 5.10.162 upstream version the io_uring code was
rebased to the 5.15-stable one. So it is likely, and it maches the
verison ranges, that the regression was introduced with this
particular changes. Ideally someone with access to the given
architecture, can verify that the issue is gone with the current
5.10.175 upstream (where there were several followup fixes, in
particular e.g. a similar one for s390x), and if not, reports the
problem to upstream.

Paul Gevers asked if the issues are gone as well with 6.1.12-1
(or later 6.1.y series versions, which will land in bookworm). That
would be valuable information to know as well to exclude we do not
have the issue as well in bookworm.

Salvatore
