Testing the new i915 driver

[Anders Bolt-Evensen]

Hello!

Today I decided to download updated source for the i915 driver on FreeBSD.
I have had problems testing that before, especially if I add myself to 
the video group prior to starting a desktop management system like GNOME.

According to 
https://github.com/freebsd/freebsd-base-graphics/tree/drm-i915-update-38 
the sources is a day old.

What I have experienced so far is the same as it was before:
When I add myself to the video group and then start GNOME, everything 
works fine until I attempt to click on Applications to bring down
the applications menu. What basically happens is that the graphical 
system stops (the clock on top of the screen stops and the system no 
longer responds to mouse or keyboard interactions while in the GUI -- I 
can press Alt+Fn to get back to the command line, but that is all), and 
when I press
Alt+F2 to get back to the command line and type dmesg > newdmesg.txt and 
then "less dmesg | grep GPU", I see the following: *error: 
[drm:pid12:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
*The entire dmesg file can be downloaded here (the boot messages were 
already deleted because of the debugging messages from DRM): 
https://www.dropbox.com/s/i7fenvvyryzlvqn/newdmesg.txt?dl=0
The pid = 613 is the PID of the "/usr/local/bin/X :0 -background none 
-noreset -verbose -auth /var/run/gdm/auth-for-gdm-eI4wlW/database 
-nolisten tcp vt09" command.

The test is being performed on a Aser Aspire VN7-791G that has an Intel 
HD 4600 and an nVidia GeForce GTX 860m grapics cards.
