After upgrading from Ubuntu 15.04 to 15.10 graphical system works visually slower and sandomly X server crashes giving error:

Probably caused by i915 driver. Two systems currently known to be affected by this bug:
a) desktop on Intel Xeon E3-1200 v3/4th
b) notebook on Intel Core i3 CPU M380
both having integrated Intel graphic cards (into CPU's), both using i915 driver.

Maybe not. /sys/class/drm/card0/error contain "no error state collected" and dmesg give me nothing interesting.
