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:

--- Comment #2 from Timoth?e Ravier <tim at siosm.fr> ---
Flash on both Firefox and Chromium triggers the freeze. Other flash based
websites (youtube for example) do not trigger the issue. Looks like the trigger
is the heavy Flash usage on a single page.

dmesg log with "updated" nouveau module

I've tried with nouveau from git://people.freedesktop.org/~darktama/nouveau
on
the same kernel (3.14.rc7.r28 (commit ea1cd65)). This still froze, but not the
first time. I had to open the website twice.
