Asus Vintage (P4S800-MX) ACPI problem?

[Jelle Posthuma]

I've been trying to reboot a new Asus Vintage barebone based on the 
P4S800-MX motherboard however until now the system just hangs before 
doing the actual reboot. The powerbutton does work at the moment, when 
pressed the system performs a powerdown perfectly.

The Asus barebone is running 5.4 release and ACPI is enabled. If 
somebody can give me a hint how to get proper /sbin/reboot behaviour I 
would greatly appreciate it.
