ACPI won't shutdown

[bsd]

Hello,

I have configured a new server and everything goes find but ACPI.

When Shutting down the server I have these messages :

…
All buffers synced.
Uptime: 5m2s
mpt0: Unhandled Event Notify Frame. Event 0x30
mpt1: Unhandled Event Notify Frame. Event 0x30
Shutting down ACPI


Then nothing !!

Computer seems to freeze for an infinite amount of time. I have to  
manually shutdown the computer with the Power button !


Any idea ?
