After a network disconnect NFSv3 mounts block the system, no reboot/shutdown possible. Processes that accessed the share are unkillable/need kill -9. Reproducible: Always Steps to Reproduce: 1.mount a NFSv3 share: "mount -t nfs 192.168.178.100:/tmp /mnt/server-tmp" 2.stop network link: "/etc/init.d/net.ra0 stop" 3.try to reboot system Actual Results: it hangs at: "killing processes using alsa" and won't do anything else if hit ctrl-alt-del: it continues shutting down but it hangs forever when this appears: "cannot stop localmount as alsasound is still up" and "Unmounting filesystems..." Expected Results: normal shutdown/reboot, no hanging processes (file-managers etc., http://www.freelists.org/archives/emelfm2/07-2007/msg00016.html) when mounting the NFSv3 share with NFSv4 (-t nfs4) or a real nfs4-share there are no reboot/shutdown problems, but file managers are hanging also.
