*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.17.2-200.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21.

If you experience different issues, please open a new bug report for those.

I've not seen this particular problem recur with later kernels.  That's not to say that bluetooth handling is perfect, for example, random droppings and reconnects, but I haven't seen this type of failure in quite a while.

Fedora Core 20
Current version 3.17.7-200.fc20.x86_64 #1 SMP Wed Dec 17 03:35:33 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Whenever I attempt to activate the bluetooth dongle (not mouse, A2DP), I get the following kernel traces :

Obs: Cannot report with ABRT because I have mod_wl and virtualbox, thus tainting my kernel.


Release: Fedora 20

Just in case: It appears to be related to my usage with blueproximity-1.2.5-12.fc20.noarch monitoring an Android Lollipop phone.

Fedora 20 has now been rebased to 3.18.7-100.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

I try to keep my kernel always updated.

The error reported by me at 2015-02-10 was running on a 3.17.8-200.fc20 kernel.

I have later upgraded to 3.18.5-101.fc20 and 3.18.7-100.fc20.  Indeed, I did not have the same bug again, since.

Okay, closing this one out then. Thanks for the reply!
