[Intel-gfx] i915: [drm] stuck on render ring

[Punk Rider]

While i was watching some online movie my kernel stuck(everything froze).
After a while system recovered and i saw these messages on dmesg:

[93395.591457] [drm] stuck on render ring

I attached the logs(dmesg,lsmod,dpkg-l , lspci, glxinfo,X.log,
/sys/class/drm/card0/error)

I'm currently experiencing these kind of errors when i'm running various
OpenGL apps(a little more complex than glxgears ;-)
These kind of errors are easily trigerred by software like Dota 2 or XFLOW
http://xflowcfd.com/ or other CAD packages under Linux(Siemens NX ,etc)


I have Asus K73S Series laptop running Ubuntu Raring.

What is the problem  with i915 driver , displaying these problems for so
many years?
Running a decent(professional) OpenGL on such a hardware is in fact
impossible( and it's not because it lacks the required OpeGL functions).

 I can provide acces to XFLOW software if it has any use in debugging these
problems.
Otherwise let me know what i can help with.
