Bluetooth of Intel AX210 is not working correctly

I’m using the latest version of Manjaro 21.1.6 (KDE) with Kernel 5.13, but the Bluetooth of Intel AX210 only works in LiveCD Mode and the second boot after installation.After the third boot , the bluetooth fails. To make the Bluetooth work again, I have to reinstall the Manjaro :sob:
I tried to upgrade the Linux Kernel to 5.14 and 5.15 but nothing changed.

Try if cold-booting helps (full shutdown, wait 10 seconds, boot it up again).

If so, you might be lucky with the latest 5.15.6 kernel which contains some patch that should help with that problem.

That kernel seems to be available in the testing branch already. So you could try switching to that and upgrade…
