Returning to the original issue: complete failure to resume, rather than 
slowness: I am affected as well.  CURRENT r333093 worked, but r333582 
fails in a manner consistent with what Pete has described, with or 
without drm loaded.  There have been a few commit messages mentioning 
ACPI in that window of history, which I will use to help me bisect when 
I have time.
