dmesg log output
I recently upgrade an Ubuntu 12.04 server OS to Ubuntu 14.04 server, kernel
3.13. My machine began locking up during SSH sessions; sometime it'd unlock and
others I just had to hard reboot the computer. I was able to get a dmesg output
that mentioned nouveau_therm_fan_set quite a bit (forgive me if I'm reading the
dump incorrectly).
I wasn't having any trouble on 3.2 or 3.8 kernels, and I have done a clean
install of 14.04 server with the same problem.
Output from dmesg of the trace on a clean install is attached.</pre>
