I'm experiencing simillar problem since I built my pc ~10 months ago. It
happens when I'm using rdesktop connected to server running windows server 2008
R2. It can happen multiple times a day.

Single gpu hang is not a big problem, because it can recover, but if it occurs
multiple times in a row, then it kills my session which is extremely annoying.


distro: archlinux

pc specs:
i5-6500
Asrock B150M-HDV
2 monitors connected to vga and dvi ports
