Bug description:
After a few minutes, the computer is going to sleep mode.
Switching to a console (Ctrl - Alt - F1) shows two error messages —

It seems this crash is reported, but I do not know if it is a red herring:
https://lkml.org/lkml/2015/3/1/6
Booting on kernel 3.16.0-34 does not resolve the issue, nor does using
upstart.
I will be bisecting the driver today to see if I can add more
information
