https://bugzilla.kernel.org/show_bug.cgi?id=215713 Bug ID: 215713 Summary: New (useless?) warning messages from BlueTooth in kernel 5.17 Product: Drivers Version: 2.5 Kernel Version: 5.17 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: aros@xxxxxxx Regression: No I've just upgraded from 5.15.30 to 5.17 and now upon pairing my BT headphones I see brand new warning messages I've never seen before: Bluetooth: hci0: unexpected event 0xff length: 25 > 0 Bluetooth: hci0: unexpected event 0xff length: 4 > 0 I wonder if it's a kernel bug or it's a valid message. The BT headphones work without any issues though. The device is 8087:0025 Intel Corp.
