Thank you for your help.

Installed xserver-xorg-video-intel-dbg package and intel-gpu-tools as 
dependency with synaptics package manager. Followed instructions from 
here: http://intellinuxgraphics.org/intel-gpu-dump.html but couldn't 
mount debugfs because system says either it's already mounted or busy. I 
can't see it mounted with
# mount

Anyway, triggered the hang-up, which is pretty repeatable, accessed the 
laptop with ssh and tried
# intel_gpu_dump > intel_gpu_dump.txt
Couldn't map MMIO region: No such file or directory

Can you please tell me what's happening?
