Hi,
there is a horrible bug in the Sony NewsOS 4.1R NFS server which totaly confuses the Linux NFS client attribute cache.
When creating directories it returns the inode of the parent dir rather the newly created one.
This bug is related to the syslog message: nfs_refresh_inode: inode number mismatch
If you have a Sony: Simply type mkdir 1; mkdir 1/2 on a Sony exported FS and you are lost ;-) It took me 6 Hours to find this ;-(
Cheers, Olaf
