Description Timothée Ravier 2014-03-20 20:33:50 UTC

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

Comment 2 Timothée Ravier 2014-03-20 20:40:32 UTC

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.
