I'm clutching at straws here.  Have you considered; file corruptions, a 
broken intrd, maybe the that version of grub does not know about the 
very latest version of ext4?  Some 64 bit stuff has just come into 
play recently.  I have run out of sensible suggestions.  (Maybe I ran 
out some time ago.)  Try writing something to the mbr of all of your 
drives, or unplug the drive(s) that you think are not involved.
