Hello all,

I'm experiencing problems with the kernel NFS server. The client hangs
on the flock call. This is Debian etch, Linux 2.6.16-1-686-smp, the
server and the client is the same machine. The directory is exported
with rw, no mount options. The lockd kernel thread is present, rpcinfo
-p reports nlockmgr registered, the firewall passes all the traffic
through.

I've googled and searched the list archive, the postings are usually
quite old (only two were from 2006 and referred to Linux 2.6), and I
couldn't see how I could further analyze the problem. I've also tried
mounting with nolock, but this apparently makes flock / fcntl to fail,
since the tools I use (automake and debootstrap, although I checked this
only with the latter) exited with an error code, and I rely upon it.

How can I fix the problem?

Thanks in advance,
