Description Kunal Bhat 2021-02-27 16:22:44 UTC
As the title suggests, the only way to toggle bluetooth on is by restarting the  bluetoothd service. Once Bluetooth has been switched off using rfkill/other frontends, it refuses to turn back on, even though rfkill reports hci0(bluetooth) as unblocked.

It works just fine on 5.10.16.

Steps to reproduce: 
Disable bluetooth with rfkill and try enabling it again.

Hardware: Intel Corp. Wireless-AC 9260 Bluetooth Adapter
Kernel Version: 5.11.1 and 5.11.2

Tried reading journalctl and dmesg outputs to no avail. Let me know if there's any logs that I can acquire.

Changing the problematic component to USB since it seems to affect more than bluetooth. My USB mouse is recognised on connecting, but doesn't seem to function unless I boot up the system with it connected.

Same problem on fedora 34 and ubuntu 21.04 with kernel 5.11.
I am using an intel ax201 card.

There seem to be Fedora downstream bugs https://bugzilla.redhat.com/show_bug.cgi?id=1944482

Was fixed in 5.12 but seems to have reappeared in 5.13
