ASRock K7Upgrade-880 with S3

	I'm prefacing my question with email to the FreeBSD ACPI list as this 
problem is to ultimately debug an ACPI problem in FreeBSD.

-- START FreeBSD Email --
I'm trying to get my desktop to STR (S3) and can't even get S3 to 
semi-powered down state. 6.1-RELEASE-p1

I've updated the BIOS to the latest version.  When I do an acpiconf -s 
3 the suspend get all the way into the AcpiEnterSleepState function 
and begins to write registers.  The last  line I see (with full ACPI 
debugging enabled):
heregs-0708 HwRegisterWrite : ----Entry

Then the power light on the case starts to blink seeming to indicate 
that it is in suspend, except I can still see output on the monitor 
and the fans and harddrives are still  running.  Then when I press 
the power button to try to bring the system back up it then displays:
heregs-0708 HwRegisterWrite : ----Exit
and then continues with a few more HwRegisterWrite and then exits the 
AcpiEnterSleepState function and then does nothing.  The system shows 
no life of coming back.  I then need to perform a cold boot, because 
if I just hit the reset button the system doesn't restart to the 
point where it gets to the BIOS screen.

My acpidump output is at:

I've fixed the errors in the asl and tried using that, but it showed 
the same problem.

dmesg:

When I do an "acpidump -dt" I see the following message displayed:
acpidump: RSDT entry 2 (sig OEMB) is corrupt

Windows isn't installed on this system so I can't compare it with 
that.  I tried suspending with Knoppix (2006-06-01) and that worked a 
bit better.  It successfully shuts off the disks on suspend, but the 
case fans and video card/monitor were still on.  When you press the 
power button again in knoppix it successfully brought the system back 
to life.  Getting it to the point of Knoppix would be a good start.

S1 in FreeBSD does work, but it doesn't shut anything down, so it's 
not really useful.

I've also tried CURRENT with ACPI-CA 20051021 with the same results.

Now for the Linux part.  Since Linux (Knoppix with kernel 2.6.17) 
seems to get at least some of the suspend/resume right I'm trying to 
figure out how to get it to display the full debug information to 
compare with FreeBSD.  I'm looking for how to do the following in 
Linux:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/acpi-debug.html
Specifically the ACPI layer and level debugging mention at the end of 
the page.

Thanks,
