Power-down problem on 5.3

[Mikkel C. Simonsen]

I have just installed fbsd 5.3 release on a Medion P4 notebook. 
Everything seems to work OK, except the power down function.

If I run "shutdown -p now" the system reboots instead of shutting down.

Before installing 5.3 I tested 4.11 (with ACPI enabled), and on 4.11 
shutdown -p worked. Is there some setting I can change on 5.3 to make it 
work there also?

Best regards,
