["Dennis L." <1495696@xxxxxxxxxxxxxxxxxx>]

Sad news: I had the same crash with the 3.19.8 kernel a couple of times now.
The obvious symptom is that the screen turns off and searches for a new signal source (HDMI/VGA/etc.).
This time it happened when zooming in Firefox (CTRL+Mousewheel) while a Youtube video was loading in a background tab.
I have tried to connect via SSH from a different machine to see if only the screen/GPU is not working correctly but it didn't go beyond login which indicates that some kind of lockup occurs.

I have attached the latest logfile from /var/crash/

Sorry for sparse/superficial information but my experience with kernel-
debugging is rather limited...
