| |
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.

Would be great if someone investigates that issue further.
Sincerely yours Burkhard
