https://bugzilla.kernel.org/show_bug.cgi?id=216686 --- Comment #12 from frc.gabriel@xxxxxxxxx --- Created attachment 303171 --> https://bugzilla.kernel.org/attachment.cgi?id=303171&action=edit dmesg bluetooth-next master branch HEAD Triggering the bug while running btmon with the HEAD of master branch from bluetooth-next does not renders the computer unusable, but disconnecting+connecting the the headset is not as smooth compared with bluetooth-next branch (which freezes computer). ``` [ 301.300526] PM: suspend exit [ 301.301469] Bluetooth: hci0: RTL: rom_version status=0 version=1 [
