I entered the search command manually. Could be that I mistyped something.
But I think, it doesn't really matter, because grub crashes before it 
the volume, anyway. The logs seem to contain control characters. Well, 
minicom dumps.

I would expect it to. My guess is, that grub finds the journal volume, 
its ext2 (which it kind of is) and expects to find some things, which are 
not there
because it's not ext2, after all.
