Just for the record, FC6 works fine when mounting an export from a 
Solaris 10 (sparc) box here. Just a stab in the dark, but maybe it's 
related to NFS version conflicts? Have you done a sanity check to make 
sure other machines can mount the solaris export? You could try editing 
/etc/default/nfs on the solaris box, setting the min and max NFS 
versions to 3 and on your linux box mounting with the option -o vers=3

That's assuming you don't explicitly need NFS V2 or V4.
