Looks like drm-kmp-default-4.9.33_k4.4.76_1-5.1.x86_64.rpm fixed only half of
the bug.

Now the the system just hangs for a moment (about 10 sec.), but then it
continues running normally. And the SC2_x64.exe isn't totally crashed any more.

Resetting chip after gpu hang

Interestingly the last line ("drm/i915: Resetting chip after gpu hang") comes
only once. Before installing drm-kmp-default-4.9.33_k4.4.76_1-5.1.x86_64.rpm
that line repeated without end about every 10 seconds.

A guess:
The drm-kmp-default-4.9.33_k4.4.76_1-5.1.x86_64.rpm didn't fixed the bug itself
but it makes the gpu recover correctly when resetting.
