You could run S.M.A.R.T. to see if the drive is dying, and of course look in 
your logs for any IO errors.  Run memchk etc if you think the memory might be 
suspect.  It could be an xfs bug too.

hard to say.  Basically this error means that xfs read something which it did 
not expect to find (think bad magic number).  I'd first try an xfs_repair.  You 
should probably get a repair binary that is less than 2 years old :)
