Comment 88 for bug 1859592

My bluetooth stopped working after updates installed on 27-09-2022. (I've set my system to do daily automatic updates and use my system every day)

dmesg errors:
[ 439.808973] Bluetooth: hci0: command 0xfc05 tx timeout
[ 439.808993] Bluetooth: hci0: Reading Intel version command failed (-110)

I tried the workaround above:
rmmod btusb
rmmod btintel
modprobe btinel
modprobe btusb

Error message:
modprobe: FATAL: Module btinel not found in directory /lib/modules/5.15.0-48-generic
