NFS issues on BETA7

[Joan Picanyol]

Hi,

I'm having issues with NFS on my BETA7 workstation, some process get
stuck in nfsfsync state, and many others are then block at select. Gnome
becomes unusable, and I get "server not responding" song on the console,
even though the server is pingable. /home is NFS mounted from a 4.10
server, NIC on the client is xl, debug.mpsafenet=0.

I've set up serial debugging, so here go some traces.

gconfd-2 is stuck in nfsfsync state:

What else should I do to debug this further?
