>Environment:
tested with stock i386 and amd64 installations
>Description:
The Intel SS4200 is a NAS storage device, which basically is a headless computer with an Intel Celeron 420 (64bit capable) CPU.

Everything is working with FreeBSD up to 7.1-RELEASE, except when shutting down the system (shutdown -p now), the system does not power off, but instead makes the rear-chassis-fans slowly go to max RPM and that's it.

It has been tested with the i386 and amd64 versions, as well as FreeNAS (0.69 based on FreeBSD 6.4, 0.7 based on FreeBSD 7.1), and they all show the exact same behavior.

Unfortunately I can not provide any more details, because I could not make FreeBSD 7.1 to boot using a serial console.
>How-To-Repeat:
Simply boot any version of FreeBSD (or FreeNAS) on an Intel SS4200 device, and issue the shutdown command (shutdown -p now).
>Fix:
It definitely is an ACPI issue, because any Linux distribution (like the one from EMC, which is optionally available for the SS4200 directly from Intel) or MS WHS does not have this problem (of course).
