Dear all,

I've been trying to figure out why FreeBSD isn't detecting C2/C3 states on
this machine. It's running on really fresh 8-STABLE. The only related
options that I can find in BIOS is C1E, and EIST, which are both enabled.
I've tried turning them on/off, but still no luck.

I've uploaded the acpidump -dt output to http://pastebin.com/fu1kh8v5 and
verbose dmesg to http://pastebin.com/jZmeNXCi.

Thanks in advance,
Nik
