NFS issues on BETA7

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?
