NFS madness on SuSE9.1

Hello SuSE folks, I'm getting this messages when I'm trying to mount remote NFS share onto SuSE9.1 box: nfs server reported tcp not available, falling back to udp nfs warning: mount version older than kernel I don't know which one causes a very strange NFS behavior: 1. The remote NFS shared directory is mounted but empty even it's not so. 2. The same mounting performed on older SuSE8.1/8.0 works without problems and any error messages. Is something in SuSE9.1 screwed in terms of NFS? I can't update our eng. dept. linux boxes to SuSE9.1 until I solve this problem. May be somebody from SuSE can respond to these questions? Thanks, Alex
