@Hans - thanks - our messages crossed in flight. I've cross posted the tags where the fixing commit should live, as well as the bug ID that brought in the fixing commit. It looks like it was brought in as normal fit-n-finish backports, so this regression should find it self-solving (knock on wood!)

Forcing an upgrade to linux-image-5.15.0-126-generic does not help. This looks a lot like https://bugzilla.kernel.org/show_bug.cgi?id=219129 but if I understand the bug tracker well, that patch has already been included in this kernel.
