If it weren't so old I'd say it could be https://bugzilla.redhat.com/show_bug.cgi?id=912062 I can't tell from the log though. Maybe dmesg would be more revealing. Another thing is to try different kernels, F21 comes with 3.17.4, but kernel-3.18.5-200.fc21 is in updates-testing repo so you could try that. And if you're brave you can go to koji and download a current 3.19 build which will have a bunch of debugging options enabled that might have some chance of further revealing the problem well enough for a bug report at least.
