Then I'm completely baffled.  I could boot off the dvd in rescue mode, and 
it mounted OK.  Booting off the hard disk started the kernel, then said it 
couldn't mount root because the filesystem used unsupported features.

The first time I did an F10->F11 upgrade.  It worked, but did not migrate to 
ext4, so I used tunefs to turn on extents.  As soon as I did that, it would 
not mount.

Then I did a clean re-install, requesting ext4.  It did exactly the same 
thing again.
