Bug Description
I have two computers at home, both running Ubuntu. One of the computers shares a folder to the other via nfs. On the client side, I mounted the drive by the following line in fstab:
192.168.
however, I found when the server becomes offline after mounting, the client side will have a lot of troubles, for example:
1. "df" takes forever to complete ("strace df" stalls at the nfs folder)
2. client computer is unable to suspend
3. file explorer (thunar) can not open any folder.
Expected behavior: system should be able to suspend, or browse files if the connection to nfs server is timed out.

When mounting with the "intr" option, you have to interrupt a stalled program (using Control-C in a terminal, for example) in order to get it to stop trying to access the server. If you instead mount with the "soft" option, NFS accesses will eventually time out without needing to be interrupted (but you may lose data if you were writing to the NFS filesystem -- the written data will not get saved anywhere because the server isn't responding.) When the server is hung, you should be able to unmount the server's filesystem using the -l (lazy) option (umount -l /opt/user1) to avoid future hangs.
