Do you have the most recent e2fsprogs? And/or what does blkid
/dev/whatever say... if it says ext4dev, try newer e2fsprogs - blkid had
a bug that caused it to say "ext4dev" when "ext4" is what we wanted.
Going forward I think we'll register both ext4 & ext4dev from the ext4
kernel module, at least for a while, so that "mount -t ext4dev" will
work still work in the transition period.
Sorry for all the hassle :)
