Hello, I tried with the latest 3.15-rc4, to no avail.
Basically, the bluetooth is sporadically available. Although, when available, it usually stays available for next reboot, even cold reboot. Apparently it takes long shutdown period / possible suspend / resume cycles to lose it again. In attachment I'll join 3 dmesg.txt. In the first one, we can see usb 3-5 failure, and BT patch loading failure. In the second, there is no longer usb failure, but BT patch loading still fails. In the third, both usb 3-5 and BT patch loading work. (strangely the usb related messages are quite different in the first dmesg - note this is first run that boots 3.15rc4). ** Attachment added: "dmesg - bluetooth / usb fail" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1260825/+attachment/4108302/+files/dmesg-20140505-1-fail.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1260825 Title: 168c:0032 ath3k built-in bluetooth cannot load firmware - sporadic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1260825/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
