Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting for once, to make this easily accessible to everyone.
CCing a few lists and people. Greg is among them, who might know if this is a known issue that 6.6.4-rc1 et. al. might already fix.
If that is not the case I guess we might need a bisection between 6.6.1 and 6.6.2 know if mainline is affected might be good, too.
Cioa, Thorsten

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.
