Heh, ouch.
Okay, so what happens is that Debian's scripts attempt to change
/boot/../grub.conf.something (xfs mounted). Changes are properly
propagated to the journal, but grub can't parse the journal, and
fails.
Ouch.
Either
1) fix grub to parse the journal (not practical, I guess)
2) do not modify grub configuration from hibernate scripts
or
3) fix hibernate scripts to sync down to disk, properly.
swsusp does not guarantee any particular state of filesystems when
system is suspended. Sorry.
