Thanks very much! And here is one entire cycle after a reboot: so hibernate, wake it back up (using the power button), hibernate with the refusal to hibernate. So, basically, includes a case where we have a successful hibernate after reboot, but an unsuccessful attempt after that. I diffed the two outputs and you can see the marks as a result. https://paste.centos.org/view/2aa60e01 The earlier case is when it goes down and comes back successfully and the later case is when it does not go down. Are there other things I should be looking at?
