[Bug 1385702] [NEW] system freezes at random when visiting a flash page in firefox like last.fm

[Brian Brodsky]

Public bug reported:

System totally freezes at random when visiting a flash page in firefox
like last.fm (not even ctrl-alt-f1 will work). I have to do a hardware
reset. I installed pepperflash and when I use Chromium do not have this
problem. I also did not have this problem before I upgraded to 14.10
from 14.04.
