Machine freeze on latest Linus kernel, seems related to nouveau

[Damien Wyart]

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.
