There are literally no commits between v2.6.24-rc3 and v2.6.24-rc4 which touch fs/nfsd/. What filesystem are you exporting? Are the nfs-utils versions the same in both cases? Also, could you get a network trace showing the failure? --b. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
