Hi. My apologies if this is not the thread to post the following:
Bluetooth does not work with kernel 5.15.2-2, it worked with 5.14.18-1
In 5.15 I can’t activate it. In 5.14 it autostarts normally.
I found a solution but it is partial because I have to repeat it every time for it to work: Pulling out the power cable (while the machine was running) fixed the issue for me (when turning on the PC again). (Source: Bluetooth unavailable after updates - Reading Intel version information failed (-110) .)

The result of rfkill is all unblocked.
Neither bluez-utils-compat nor bluez-utils fixes the problem.
Thanks in advance.
