dmesg 6.11.0

Comment 2 The Linux kernel's regression tracker (Thorsten Leemhuis) 2024-10-01 06:33:44 UTC

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)?

Comment 3 sander44 2024-10-02 07:24:47 UTC

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

Comment 4 Denis Shkuratov 2024-10-18 12:12:44 UTC

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
