sarge with linux-2.6.17-3 as an nfs server. Another machine with woody and linux-24.4.24 fails to mount the exports from the sarge machine. mount simply hangs without errors.

syslog on sarge says "rpc.mountd: authenticated mount request from xxx.yyy.zz.aa:868 for /xxyyzz (/xxyyzz)" tried rpc.mountd with --no-nfs-version 3.

any ideas?
