The aac firmware has recently moved to a system where status changes are
no longer delivered to the driver in 'plain text' format.  Instead, 
encoded messages are sent to the driver for relay to apps like aaccli.
The driver only knows how to decode a very small subset of these 
messages, and it doesn't know anything about the kind of messages that
you would be getting in this case.  So it has nothing to print out.

Adaptec does provide a daemon that can recieve the messages and convert
them into multi-ligual text for delivery to the syslog.  It is under the
GPL, and I have not ported it yet.  It also requires several
modifications to the aac driver that I have not finished testing yet.
