nfs locking broken

[Palle Girgensohn]

Hi!

It seems that NFS locking is broken for the combo of 4.11 or 5.4 server and 
6.x client. Apps like eclipse and firefox fail to start with my home dir on 
a 4.11 server and a 6.x client.

Problem shows in that firefox hangs, as does eclipse.

I've tried the following combinations:

client   server
4.11     4.11      OK
5.4      4.11      OK
6.0      4.11      Hangs
6.1pre   4.11      Hangs

4.11     5.4       OK
5.4      5.4       OK
6.0      5.4       Hangs
6.1pre   5.4       Hangs

6.0      6.0       OK
6.1pre   6.0       OK


Any ideas about this, or whom to contact?
