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
