Patrick, please recheck /etc/default/grub and be sure it is as what you
set it to that resulted in successful hibernation and reboot.
All I know is that I changed GRUB_DISABLE_RECOVERY="false" (from
"true") and rebooted. That was the only change. When I tried
hibernation it worked (i.e. resuming worked). In fact it worked at
least twice, then *with no further change* didn't work. Given the
random nature of this it's hard to ascribe causality. One can never
discount HW of course, but there are no other symptoms. The system is
an i7 CPU in an Intel mobo with 16GB of RAM and root on an SSD
formatted as btrfs. Video is an Nvidia GeForce GT 630.
