This might be the same issue as the fixed one by
https://git.kernel.org/linus/0a6ad4d9e1690c7faa3a53f762c877e477093657
(cf. https://bugzilla.kernel.org/show_bug.cgi?id=205015)

Would you be able to apply this patch on top of the 6.11-1~exp1 (you
can use the debian/bin/test-patches script) and see if that resolves
your issue?

Regards,
Salvatore
