Furthermore this will now scream properly on all platforms if we don't have hw counters enabled. v2: Adjust to the new names.

I just tested my BDW machine with the command provided in comment #1: ./kms_flip --run-subtest rcs-wf_vblank-vs-dpms-interruptible And I can confirm that patch "drm/i915: properly reenable gen8 pipe IRQs" fixes the bug for me, so I'm closing the bug. If it still happens, please reopen.
