Steps:
-------
1. Execute IGT test manually (no timeout is used):
./gem_mmap_gtt --r swap-copy
2. Wait 100 hours

Actual results:
----------------
2. Test is still not finished after 100 hours (IGT is still running - DUT is
not freezed)
dmesg shows the same logs on all platforms, example on SKL:

Expected results:
-----------------
2. Test is not so long

Info:
-----
I can't attach dmesg due to its size
There is no log from IGT
