| |
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
