Subject: [Bug 215713] New: New (useless?) warning messages from BlueTooth in kernel 5.17
Date: Mon, 21 Mar 2022 12:55:16 +0000 [thread overview]
Message-ID: <bug-215713-62941@https.bugzilla.kernel.org/> (raw)
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@vger.kernel.org
Reporter: aros@gmx.com
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. Wireless-AC 9260 Bluetooth Adapter.
