Yes, thanks for the kernel suggestion. I was planning to install 3.6.9 from
experimental today but first I wanted to give the latest LTS kernel 3.4.x series
a shot. Last night after having another full freeze, I installed the 3.4.23
kernel, but met with the same results of constant nouveaux syslog errors.

I've installed 3.7.1 from experimental today, and so far (30 min) have not had a
single nouveaux message or freeze. I will continue using this kernel for the 
next several days if it is problem-free.

One issue I have is I can't seem to install the headers I need for Virtualbox to
run.

$ sudo apt-get -V -s install -t experimental linux-headers-3.7-trunk-amd64

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 linux-headers-3.7-trunk-amd64 : Depends: linux-kbuild-3.7 but it is not installable
E: Unable to correct problems, you have held broken packages.


It seems the linux-kbuild-3.7 package is not in the experimental repository.
Could you please advise how I might get the needed headers installed?

Thanks
