Dear Ortwin,

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.
This has been already reported in *[PATCH] Bluetooth: Apply initial
command workaround for more Intel chips* [1].
As I replied there, on what device do you experience this, and how can
it be reproduced?
I have a Dell Latitude E7250 with the Bluetooth device 0x0a2a, and
everything works fine under Debian sid/unstable with Linux 5.15 up to
5.16-rc6.
Bus 002 Device 003: ID 8087:0a2a Intel Corp. Bluetooth wireless
interface
Kind regards,
Paul
