The test igt/gem_exec_suspend/basic-s3 does not wake up from suspend when
invoked as part of the testlis tintel-ci/fast-feedback.testlist

Manual wake up is needed, afterwards test reports pass.

I am in the process of finding the minimal test case.

So far, the smallest test set that triggers this:
sudo IGT_TEST_ROOT=`pwd`/intel-gpu-tools/tests ./piglit/piglit run igt -o
results -l verbose -s --test-list
intel-gpu-tools/tests/intel-ci/fast-feedback.testlist -t gem_exec

While specifying tests separately, the hangup does not occur:
