Hi, this is your Linux kernel regression tracker.

5.16.11-16 sounds like this is a distro kernel that might or might not
be patched. Or is 11-16 just meant as a range. Could you clarify?

Hmmm. Of course ideally all regressions get fixed, but that beeing said:
5.16 will likely be EOL in round about two weeks anway and getting to
the root of this problem might take some time and effort. That's why I'm
not sure myself what's the best way forward here. Maybe testing 5.17 to
see if the problem still shows up would be good; bisection would help,
but I guess that will be hard here. But I guess there is one thing that
could help: could you maybe decode the panic you have as described in
this document:
https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html

Ciao, Thorsten
