During boot I have this message:
[ 5.691087] Bluetooth: hci0: unexpected event for opcode 0xfc2f
When bluetooth end to work the only solution is to reboot. If during the
boot there is the error bluetooth works, if error doesn't appear the
bluetooth will not work and the possible solutions are:
- Enter in BIOS, disable all wifi chips, reboot, reboot entering bios,
enable wifi, reboot and bluetooth works until first power save.
- Reboot in Windows, make logon in windows, connect a bluetooth device
(in my case, the mouse), reboot in linux.
This is the dmesg of a boot with working bluetooth:

Subject: Bug#632960: bluetooth: Bluetoothd dies after restoring from
hibernate PM
Package: bluetooth
Version: 5.62-2
Followup-For: Bug #632960
Dear Maintainer,
Same situation.
When any powerreduce act (p.e. display shutoff) the Bluetooth goes off, as
WiFi, but on resume WiFi restarts normally, bluetooth no.
bluetoothctl reports no controller on list command.
blueman fails to start.
blueman-adapters 12.39.01 ERROR Adapter:54 __init__ : No adapter(s) found
