Subject: [Regression]: Bluetooth: btusb: hci command tx timeout
Date: Mon, 9 Apr 2012 19:17:56 +0200 [thread overview]
Message-ID: <20120409191756.f6eeea4e.lolium@gmx.net> (raw)
Hi all,
since Linux 2.6.29 my integrated Bluetooth hostcontroller does not work
anymore. Its a hardwired Broadcom chip connected via USB in an IBM
Thinkpad T43 and supported by btusb.
While scanning for devices and pairing mostly succeeds, the process
stalls after that repeatable, so its impossible to use the connection.
Kernel message buffer shows:
Bluetooth: hci0 link tx timeout
Bluetooth: killing stalled connection XX:XX:XX:XX:XX:XX
Verified with bluetooth mouse, cellphone and another linuxbox with
bluez, kernel 2.6.30-3.4-rc1, bluez 4.96, 4.98, 4.99, git.
