my fstab-entry: 192.168.0.50:/mnt/nfs_1 /mnt/nfs_1 nfs rw,hard,intr,user,nodev,nosuid,exec 0 0
from man mount: [snip] The process cannot be interrupted or killed unless you also specify intr. [/snip]
I can't interrupt any process that accessed the NFS-server while shutting down the server, although intr is specified. _That's_ my problem. :)
