For the record, I submitted a patch to address the issue with the test
suspending before skipping.  Petri already reviewed and pushed to igt.

31f71d62d5ff ("igt/kms_pipe_crc_basic: Skip test before system suspend")

Agreed.  The issue is more related to the recovery of the suspend than the
read_crc itself.  Just need to mention, though, that bsw-n3050 has connectors
attached, as well as VGA, meaning that it's not a case where my patch will make
igt skip.

We are also discussing on the list a way to reduce the overhead provoked by the
thousands of dp_aux_ch timeout messages below:
