>Description:
When acpicpu(4) is enabled in the kernel, the machine will stop booting when 
acpicpu(4) gets autoconfigured.  The screen goes blank and the machines just 
does nothing (or nothing visibly).

NetBSD 5.99.55 worked fine on this machine, the problem happens with 5.99.56.

Here is a dmesg (with acpicpu(4) disabled):
