can't mount anymore..

[Daniel Nordin <tiresome@home.se>]

I installed xfs on a Pentium Pro with a Promise TX-133 IDE 
controller, Slackware 8.0 and kernel 2.4.17-xfs. Then I 
made a xfs partition on a 80Gb IDE HD. It worked just fine.

Now I have an Alpha W/S with Redhat 7.1, the same IDE 
controller and the same kernel version.
But now when I try to mount the xfs-partition it says:

XFS: Trying to mount file system with 4096 bytes
XFS: Only page-sized (8192 bytes) blocksize currently works
XFS: SB validate failed

so... what is my problem and how do I solve it ???
