--- Comment #38 from Robb Ebright <robbt-UEAdIY/G9B/YtjvyW6yDsg@public.gmane.org> ---
I ran into a similar bug with a recent Debian install. It occurs only when I
plugged in a monitor into the DVI port. It works fine with the HDMI port as I'm
using it to type. But it freezes with the following error.

I'm installing the proprietary drivers so but I wanted to provide this
confirmation/documentation in case it is helpful to anyone trying to solve
this. In an ideal world I would use the free software drivers as well but there
is evidently some issue with the software that is causing it to crash.
