Call traces of hard lockup

Just had a hard lockup while using my bluetooth mouse. I couldn’t find similar bug reports.

Here are some call traces I could find in the Fedora problem tracker:

Please try one of the latest kernel releases (or, even better, linux-next.git), 3.15.7 is not such.
Comment 2 Marcus Husar 2014-08-14 19:50:02 UTC 
With kernel 3.16 and quite new userspace (Fedora 21) I haven’t seen any bluetooth-related problems, yet.
Comment 3 Alan 2014-08-21 17:57:19 UTC 
Was fixed by 3.16 - known bug
