Re: Kernel Config Trouble

It is also posible that you are specifying the wrong drive and or
partition.  I would look for "Partition check:" and the lines that
follow.  Make sure that looks sane.  You should be able to use
Shift+PageUp to see this if it scrolled by.

You can pass the "rootfstype=xfs" kernel option to force it to use xfs
vs triing all the compiled in file systems in successtion until one
works.  I would be supprised if this worked though.
