OK, so it's unlikely to be a UUID problem.
The first thing I'd do is get rid of the "quiet" and "splash" options.
That might show you a bit more of what's going on. It might be an idea to
increase the timeout value as well - make sure there's enough time for the
screen to catch up.
I guess you've already checked that /dev/md0 is actually functional - if
the mirror is degraded, one of the partitions is unlikely to boot.
It's worth checking fdisk-s output there are no other partitions as well -
it's quite embarrassing to find you're not booting from the partition you
thought you were (not that I'd ever do that, oh no).
Errr - that's about all that occurs to me at present. Let us know if
anything comes from the above :-)
