I decided to change its IP but forgot to umount NFS shares. When trying to 'umount /mountpoint-of-a-nfs-share' without -f I got mount hanged up infinitely. After successful umount -f I got the inability to log in via ssh, hanged up midnight commander, and 'reboot', issued from local console also hanged up. (Probably some other side effects had place too). >How-To-Repeat: Repeat similar actions. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
