Comment 2 Thomas Spura 2014-04-28 09:03:03 UTC 
2 seconds after this crash, I got another one with flags:GW, which doesn't allow me to report it as the kernel seems tainted.

But it is crashing with CPU: 0 PID: 671 at drivers/net/wireless/iwlwifi/dvm/main.c:1997 iwl_wake_sw_queue+0xa2/0xb0 [iwldvm](), so both should be related to each other...

At the time of both crashes, my smartphone was using the hotspot of my laptop.

*********** 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 3.14.4-200.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 experience different issues, please open a new bug report for those.
