Greetings -
With mainline kernel 6.6.2+ (and 6.1.63, etc), bluetooth is inoperative
(reports "opcode 0x0c03 failed") on my motherboard's bluetooth adapter
(Intel chipset). Details below.
I reported this in a comment tacked onto bugzilla #218142, but got no
response, so posting here as a possibly new issue.
Details, original email:
----------------------------------------------------------------------
I have a regression going from mainline kernel 6.1.62 to 6.1.63, and
also from kernel 6.6.1 to 6.6.2; I can bisect if patch authors can't
locate the relevant commit. In the most recent kernels mentioned,
bluetooth won't function.
Hardware: ASRock "X470 Taichi" motherboard - on board chipset.
lsusb: ID 8087:0aa7 Intel Corp. Wireless-AC 3168 Bluetooth.
dmesg: Bluetooth: hci0: Legacy ROM 2.x revision 5.0 build 25 week 20 2015
Bluetooth: hci0: Intel Bluetooth firmware file:
intel/ibt-hw-37.8.10-fw-22.50.19.14.f.bseq
Bluetooth: hci0: Intel BT fw patch 0x43 completed & activated
bluez: Version 5.70, bluez firmware version 1.2
Linux kernel firmware: 20231117_7124ce3
On a working kernel (such as 6.6.1), in addition to the dmesg output
above, we have this:
dmesg: Bluetooth: MGMT ver 1.22
Bluetooth: hci0: Bad flag given (0x1) vs supported (0x0)
On a failed kernel (such as 6.6.2), instead of the good output above, we
have:
dmesg: Bluetooth: hci0: Opcode 0x0c03 failed: -110
Bluetooth: hci0: Opcode 0x0c03 failed: -110
...
repeats several times as bluez attempts to communicate with hci0.
----------------------------------------------------------------------
Since that email was sent, kernel firmware has been updated to
20231128_aae6052, and kernels 6.1.64 and 6.6.3 have been tried with no
change observed.
