>Description:
I was asked by Jared McNeill to test the ACPI functionality of the NetBSD 
4.99.60 (GENERIC) kernel he was working on. My computer is a Compaq ProLiant 
DL360 G1 with dual P3/1GHz processors, 1152MB ram, and a ServerWorks chipset. 
Using the NetBSD-4.0-RELEASE (GENERIC) kernel, my computer would freeze during 
boot if ACPI was enabled in the kernel. The NetBSD 4.99.60 (GENERIC) kernel 
booted fine with or without ACPI, however when I ran 'shutdown -r now', it 
would kill all processes, unmount the drives, and then just sit. It would not 
automatically reboot with or wihout ACPI enabled. If ACPI was enabled, I would 
have to hold the power button for 4 seconds to turn the power off at that time. 
If ACPI was not enabled, momentarily pressing the power button would turn the 
power off immediately at that point.
>How-To-Repeat:
Install NetBSD-i386-4.0-RELEASE on a Compaq ProLiant DL360 G1
Copy the NetBSD 4.99.60 (GENERIC) kernel into /
Reboot
SU to root
Type 'shutdown -r now'
>Fix:
A workaround exists: Manually pressing the power button to power-cycle the 
computer.
