I am using GRUB2, not GRUB2-EFI.

I was unable to get either rd.debug or plymouth.enable=0 to work; instead i
removed the 'splash' and 'quiet' parameters altogether, which avoided the
splash screen as well as gave some additional messages, and added kernel
parameters 'debug' and 'ignore_loglevel' which provided a lot of debug
messages.  I am attaching a couple of files.  One attachment is a screenshot
taken at the time of resume failure showing that PM was not able to locate the
snapshot and failed as a result; teh other is a collection of various pieces of
data:
- fstab, showing the swap files
- output of blkid for both of the swap files
- grub.cfg showing that the resume parameter had the correct uuid

It appears that PM was able to find the correct partition, but was not able to
find the snapshot.

If you feel that additional dracut parameters woudl be useful in resolving
this, it would be helpful for you to provide the paramteres that you would find
useful as well as a methodology for getting them to dracut, as nothing that i
have tried seems to have worked, though i have tried various things as
described in man pages.
