[Debian 10.1 stable]
Seit kurzem (wahrscheinlich nach dem dist-upgrade auf Debian 10.1) gibt mein Rechner aus:
, kurz nachdem ich ihn eingeschaltet habe, noch bevor LightDM erscheint.Bluetooth: hci0: unexpected event for opcode 0xfc2f
Code: Alles auswählen
# journalctl -xb
https://lkml.org/lkml/2019/6/6/868gibt aus:Sep 15 05:54:36 <hostname> kernel: Bluetooth: hci0: unexpected event for opcode 0xfc2f
Kann ich also diese Fehlermeldung beruhigt ignorieren?>> The 0xfc2f command is never issued by btusb.c or btintel.c actually. It is a command to apply the BDDATA information used only by Intel AG6xx devices which are UART only. So I am almost certain that this is a bug in the hardware / firmware and the patch above just started to highlight it. The trace will show if that is the case.
…
There is actually nothing wrong with it and the firmware bseq file clearly says that it is expecting a command status followed by the vendor event. The driver however for simplicity reasons is using __hci_cmd_sync_ev and just waiting for the vendor event since the command status doesn’t offer any useful information in the success case.
Now I think that in the case of __hci_cmd_sync_ev with an extra event expected, we should not print this error when receiving the command status since that is clearly a valid response. How to achieve that, I don’t know yet. Maybe Joao Paulo has an idea.
