Suspend still failing to start up again.  Screen is blank and ssh finds
no path but computer looks and sounds like it is running normally.
PC is 6 months old and suspend worked flawlessly until roughly 2 to 3
weeks ago.   This is Fedora 26 using always the latest Fedora provided
kernels or Linus' kernels compiled by me.  Both started to have resume
failures.  vmlinuz-4.13.15-200.fc26.x86_64 works usually (failed once
out of 3 or 4) and later ones never work(? fail 2 out of 2).

It seems a suspend problem was back-ported starting about vmlinuz-
4.13.15 because I never saw failure earlier, eg. vmlinuz-4.13.5--14-
200.fc26.x86_64

Also the chance of resume failure seems to increase the longer I wait,
like resume will probably work after 10 or 20 minutes but after 12
hours it seems to fail almost always.  But to be certain, this would
need much more testing!
