3.13 is a fairly old kernel. Can you reproduce it with a more recent one, like 4.0 or drm-intel-nightly from http://cgit.freedesktop.org/drm-intel?

If that's possible to compile drm-intel-nightly for my kernel version, which comes with Ubuntu LTS, then I'm gonna try it. Is there some fix in 4.0, which you think remind of that problem?

Unfortunately, we cannot support such an old version of the kernel as you have. You should open a bug report with Ubuntu for support with their LTS kernel.
