Description
A specific web page, with some flash content triggers an Xorg freeze (100% system CPU on one core). I reproduced the issue 4 times in a row right after booting.
The specific web page: http://rue89.nouvelobs.com/rue89-culture/2014/03/20/annees-rap-a-quitte-cite-parler-bieres-baise-suicide-250788
