I've attached the journal.txt as requested. One more point to add - enabling/disabling flight mode within Ubuntu does not resolve the problem; but if I enable/disable on the laptop (there's a key sequence on this Entroware Apollo) then it gets Bluetooth working again. This might suggest that resetting the hardware is necessary to resolve which might indicate that the linux bluetooth support has crashed the silicon.

Mouse (logitech M720) stopped mid scroll. Never had any problems with this mouse under Ubuntu before. Workaround: Reboot fixes the problem. Switching in and out of airplane mode gets bluetooth working again Frequency: Second time this has happened since upgrade from 22.10 (about 2 weeks ago) Limited knowledge fault tracing: >sudo systemctl restart bluetooth doesn't make any difference >rfkill shows no bluetooth device >lspci ... 3b:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78) ... Ubuntu settings - show bluetooth is off, but I didn't disable it and it can't be re-enabled. So I assume the driver has crashed, but I don't know how to find out more about this. Could collect some more info next time it happens if someone tells me what to do. >lsb_release -rd No LSB modules are available.
