IBM Integrated Bluetooth IV Product: Drivers Version: 2.5 Kernel Version: 3.6.8-030608.201211271040 i386 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth AssignedTo: linux-bluetooth@xxxxxxxxxxxxxxx ReportedBy: linuxkbugs@xxxxxxxxxxx Regression: Yes Bluetooth connections do not work: the rx channel works, while the tx stalls after a few seconds of connection, and timeouts disconnecting the connection after approximately one minute. The device is 0a5c:201e Broadcom Corp. IBM Integrated Bluetooth IV, as seen on lsusb; it uses the generic btusb driver. This bug has been reported in the following places too, but I could not find any follow-ups from kernel developers, so I'm reporting it on this Bugzilla too. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/950413 http://permalink.gmane.org/gmane.linux.kernel/1279113 http://www.spinics.net/lists/linux-bluetooth/msg23498.html I've tested the latest mainline kernel 3.6.8-030608.201211271040 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.8-raring/ , this should be the latest according to the timestamp, please tell me if I need to test with another version. I'm using Ubuntu 12.04 on an IBM ThinkPad X41.
