Nouveau - May 2014 - Machine freeze on latest Linus kernel, seems related to nouveau

Hi,

I am running the latest kernel from Linus. Once yesterday and once
today, I got a freeze of my machine. The first time, I could reboot
with sysrq, but not the second one (completely unresponsive). The
first time,, there was nothng in the logs, but today, I got some
traces which I attach to this email.

I can provide more details if needed ; the card is GeForce 9600 GT and
the OS Debian Sid.

Thanks in advance for any feedback.

Damien Wyart

Hi;

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 :

Amazing. I get the same thing in chrome on my setup (G96).

This is on top of a 3.15-rc5+ kernel.

Normally these things are very hard to debug because they're
~impossible to reproduce. However this website seems to do the trick
(I'm guessing with the help of the youtube embeds).

Ben, any advice on debugging? (Or even better, an idea as to what's
wrong... I seem to recall this happening a lot a while back and then
it magically fixed itself for a while...)
