System: NetBSD 3.99.11 NetBSD 3.99.11 (LANFEUST_ACPI) #1: Thu Nov 10 17:28:42 CET 2005 amd64
Architecture: x86_64
Machine: amd64
I recently made some tests with ACPI on my Tyan S2885 workstation and noticed
that the HPET (High Precision Event Timer) timer PNP0103 is not listed in
acpidevs list.

njoly@lanfeust [~]> dmesg|grep PNP0103
PNP0103 at acpi0 not configured

Specifications from Intel:

Boot an kernel with ACPI+ACPIVERBOSE enabled on a Tyan Thunder S2885.
