I repeat the command and get the following error: 
(I press <UP><RETURN> after the previous fwcontrol exit about 1 second)

Sorry that I'm not sure what do you mean?

When I test fwcontrol yesterday and today, there is no other message
dump (the fwcontrol just show something, exit, then return to prompt)
, and there is nothing in /var/log/message.

I use the same tape and machine.

Thanks for your help, what can I do to get more information?
