NFS-root NFS mouting problem

Hi,

I'm trying to net-boot a system (root NFS) here, but I run into trouble mounting NFS filesystems *after* the root filesystem has been mounted (over NFS).

Both server and client are 2.4.18 on i686 - everything works great if I boot from a disk and mount the home filesystem via. NFS.

Booting the client via. pxelinux, the following happens:
*) Kernel loads, gets IP, ...
*) / is mounted (rw) via NFS
*) Init-scripts start running, brings up eth0, lo, portmapper, syslog, NFS locking services, all is ok...
*) Init-scripts attempt to mount the home filesystem from the server, just like it would if booting from the disk. This fails with the following errors:
--------------------------
Mounting NFS filesystems: exec: Stale NFS handle
mount: Stale NFS handle
exec: Stale NFS handle

touch: creating '/var/lock/subsys/netfs': Stale NFS handle

Mounting other filesystems: exec: Stale NFS handle
dup2: Bad file descriptor
exec: Stale NFS handle
--------------------------

I tried net-booting to single-user mode, which works perfectly well. Then, mounting *any* NFS filesystem will lock the system with stale NFS handles again.

The *really* interesting thing is, that after one such failed attempt, I must re-start the NFS *server*, otherwise the client gets a "Root-NFS server returned error -13 while mounting /netboot/falcon"... But I suppose this problem will go away with the first one.

Anything I can try ? Any ideas ? Need more information ?
