I think you should use "reportbug" to report the bug to the kernel
team.
You may like to try building a Debian kernel package from upstream
source:
https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-kernel-org-package
If that results in a package that works for you, that's something to
report in the bug.
If it doesn't, you can go back through the 6.1 kernel releases until
you find one that does work. Then you can report that.
Once you find an upstream source version that doesn't work, you can
use "git bisect" to go back and find the version that DOES work, and
then further bisect things until you find the exact commit that
causes the issue for you.
The Debian kernel team may then be able to backport a fix to the
bookworm stable kernel, and submit it upstream if necessary.
Alternatively, the kernel team may have a way for you to step
through individual changes in between Debian packages 6.1.0.12 and
6.1.0.13.
Good hunting!
Thanks,
Andy
