dmesg, debug kernel, after the lock up occurs and before the computer hangs for goo

With an up-to-date fedora, with the linux 3.16.0-0.rc0.git5.2.fc21.x86_64 (even with the +debug linux), if I browse the www with firefox, a CPU lockup happens, randomly.

I was not able to trigger that bug otherwise.

dmesg, non debug linux

I was able to trigger the bug with the midori web browser (webkit based), but after much more time.

still happening with 3.16.0-0.rc3.git0.1.fc21.x86_64
Comment 3 sylvain.bertrand 2014-07-21 02:23:10 UTC 
closing because it seems that linux 3.16 does not work with my overclocked CPU (2.5->2.7Ghz). OC CPU works fine in linux 3.15
