Hi
On all 5.15 kernels the Intel Bluetooth no longer works. All was fine in 5.14.
Apparently the quirk is needed for this device.
vanilla 5.15.5:
Bluetooth: hci0: Reading Intel version command failed (-110)
Bluetooth: hci0: command tx timeout
with patch:
Bluetooth: hci0: Legacy ROM 2.5 revision 1.0 build 3 week 17 2014
Bluetooth: hci0: Intel device is already patched. patch num: 32
Please apply to stable too.
Thanks
Ortwin
