No idea...

So it works using the upstream Linux kernel.
Maybe double check, and then file a bug with the Debian kernel if you
can still reproduce? Assuming that the Debian kernel maintainers care
about fixing the Debian old-stable kernel...
I could talk about all of the massive number of security fixes that
aren't backported to 5.10 and so are unsecure, but I assume you know
that. Friends don't let friends use 5.10; there are reasons why
enterprise Linux customers pay $$$$$$ to Red Hat and SuSE. It's
*expensive* to safely use ancient kernels. :-)
For the record, at the moment as the ext4 maintainer I really only pay
attention to 6.1, 6.6, and 6.12 LTS kernels. And there are a whole
bunch of xfstests which fail with the older LTS kernels. Compare:

(And 5.10 and 5.15 are even worse, but I don't bother with them any
more. Volunteers to manage the older ancient ext4 for stable kernels
would be greatly appreciated. I don't have the time.)
