>Description:
Enabling 'acpicpu' on my server causes the ichlpcib0 to not be configured 
properly (specifically, the Watchdog support is not present...I didn't check 
hpet and other items).

Without acpicpu:
...

>How-To-Repeat:
In kernel configuration, add:
acpicpu*       at acpi?                # ACPI CPU
