Thank you for the report.

Can you please, after a boot with the new kernel and Bluetooth not working, do:
 # journalctl -b --no-hostname > journal.txt
 # xz journal.txt
then attach the compressed journal file 'journal.txt.xz' to this bug. [The exact filename does not matter].

Thank you for that. There is a series of Bluetooth messages, the last 'timeout'.

looks like Intel is working on it:
Comment 5 Thomas Backlund 2021-12-16 22:20:36 CET
I've submitted a kernel-5.15.8-1.mga8 to Core Updates Testing (currently building)...

It should show up on the mirrors in a few hours...

Please test if it works any better...
