           Summary: [BXT] igt gem_fence_thrash at bo-write-verify-threaded-y
                    & x are showing time out.

Dmesg log

The following test are passing in stand alone mode (executing from tests)
gem_fence_thrash at bo-write-verify-threaded-y &
gem_fence_thrash at bo-write-verify-threaded-x.

If you execute the test using ./run-test.sh -t
gem_fence_thrash at bo-write-verify-threaded-y -t
gem_fence_thrash at bo-write-verify-threaded-x 

They show a time out failure.

But if you run them directly on test on igt, they are going to pass, so the
problem seems that they are taking more time that the scripts allows.

Output:
 sudo ./gem_fence_thrash --run-subtest bo-write-verify-threaded-y

And the eDP never comes back in a normal way, we just get overlapping.
