Calin:

Thanks for the reply. I've already checked that, and it looks to me as if
everything that should be running, is running. 

here's rpcinfo -p on the NFS server machine:
# rpcinfo -p
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100005    1   udp    674  mountd
    100005    1   tcp    676  mountd
    100005    2   udp    679  mountd
    100005    2   tcp    681  mountd

and here is the same thing on the client where nfs mounts aren't working 
(BTW, they ARE working from other clients, still):

# rpcinfo -p 128.2.2.25
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100005    1   udp    674  mountd
    100005    1   tcp    676  mountd
    100005    2   udp    679  mountd
    100005    2   tcp    681  mountd


one of my co-workers who uses fc4 on his desktop was able to mount it
on his client, and it is still mounted from other (non-linux) systems
in the server room, so it looks to me like a problem on the client machine.
since the problem appeared only after the latest kernel update, it seems
likely to be related to that.

Thanks for your assistance!
