There is an answer to this in the FAQ.

If this partition is formatted with another cluster size then 4K you can't 
read it (yet).
Irix uses a default of 512Bytes.

So if you want make it interchangeable you will need to format it with a 4K 
cluster size.
This is because on ia32 Pagesize==Clustersize. And XFS currently can not 
mount disks where Clustersize is larger or smaller then pagesize.
