Does this cause any problems, or is it just a error msg you noticed? And is
this a new error msg (and thus a regression)?

It's just a message I saw. I don't see it causing any problem.

Have same issue on 6.11.3 on Fedora 40

[  492.013592] Bluetooth: hci0: Opcode 0x0c24 failed: -110
[  492.013601] Bluetooth: hci0: command 0x0c24 tx timeout
[  494.125556] Bluetooth: hci0: Opcode 0x0c24 failed: -110
[  494.303623] usb 1-8: reset high-speed USB device number 2 using xhci_hcd
[  494.517351] Bluetooth: hci0: Failed to claim iso interface

Bluetooth is working, but suspend is not - PC doesn't wake up from sleep.
Disabling bluetooth fix this problem.

My bluetooth card is Mediatek mt7921

Have no issues so far on 6.10.12 kernel version

Be glad to provide any info to fix suspend issue, because it's kinda annoying
to live with
