Hi Joseph, Thanks for the quick reply.
I installed the kernel v3.13-rc3-trusty, and booted several times. There seems to be no change compared to previous 3.11 kernel from Saucy, i.e. on 4 boots, BT failed 3 times and succeeded once. So I tag this bug with 'kernel-bug-exists-upstream' and mark it 'Confirmed'. $ uname -a Linux zyratastic 3.13.0-031300rc3-generic #201312061335 SMP Fri Dec 6 18:37:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux ** Tags added: kernel-bug-exists-upstream ** Changed in: linux-firmware (Ubuntu) Status: Incomplete => Confirmed -- 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-firmware/+bug/1260825/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
