might be useful for others. Searching dmesg I found that I had XID errors
coming from the nvida module when this problem occurred. Searching for XID
errors, I found this link on one of the Ubuntu forums (
http://ubuntuforums.org/showthread.php?t=1163786). This led me to try
adding this option to the nvidia module (in /etc/modprobe.d/nvidia.conf):
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
I did this four days ago and have yet to see the same failure. I'm also
pretty sure my problem is not heat related. I've never seen my GPU go over
57C. I'll post again if the problem resurfaces.
