This is XFS saying "I read the first sector ondisk, and it
doesn't have the XFS superblock magic number in the first
word".  This is the very first IO request XFS issues on mount.
The read has completed without an error, its the contents of
the buffer we get back that isn't an XFS superblock.

So, not a XFS compiled-in/module issue as was suggested, and
not an XFS issue at all - looks like there's some problem in
getting the root device identifier into the kernel I'd guess.

The "unknown" & (0,0) there is probably a hint, I've never come
across that before though.

cheers.
