Subject: Re: Machine freeze on latest Linus kernel, seems related to nouveau

After further tests, I can reproduce the problem on 3.14.4 also,
mainly by visiting the following URL with Firefox (29.0.1) :
http://lavieestmaloptimisee.blogspot.fr/

Firefox becomes unresponsive and I get some messages in the kernel log :
