FIXED!
In /etc/initramfs-tools/conf.d/resume the swap drive UUID was not correct.
Hibernation will occur correctly, however on resume it will fail nearly
silently and proceed with a normal boot instead. The only indication will be
"PM: Resume from disk failed." in dmesg.
To fix, correct the UUID in the config file and rebuild initramfs as
follows:
1) Get the UUID for the swap device:
blkid `swapon -s | awk '/dev/ {print $1}'`
2) Edit /etc/initramfs-tools/conf.d/resume (as root) and replace the
UUID there with the correct one.
If the UUID listed is already correct, add a comment and attach pm-
suspend.log and dmesg
