Unit attention commands are getting ignored when a dvd is
replaced, resulting in errors when accessing the new dvd.
This problem occurred when a system is booted in rescue
mode via dvd and the dvd is then replaced with another dvd.
Subsequent commands to a filesystem on the dvd, such as
'fsck' and 'restore' report errors.
Solution suggested by Mike Christie.
