powernow, powerd and phenom 9600 on amd/ati 780g ?!

[Eugene Kazarinov]

Hello.
ph00# uname -a
FreeBSD ph00.yaol.ru 7.0-STABLE FreeBSD 7.0-STABLE #1: Mon Apr 21 20:17:50
MSD 2008     kamuzon at ph00.yaol.ru:/usr/obj/usr/src/sys/KMD  amd64


I clone this system twice and ran it on two different machines.


1. GigaByte GA-MA78GM-S2H (on 780g chipset) and AMD Athlon BE-2300

in logs after systemboot:
cpu0: <ACPI CPU> on acpi0
powernow0: <PowerNow! K8> on cpu0
cpu1: <ACPI CPU> on acpi0
powernow1: <PowerNow! K8> on cpu1

"dev.cpu.0.freq_levels: 1900/50000 1800/45492 1000/20378" looks good and
powerd -v (then I test it) works fine.

sysctl dev.powernow
dev.powernow.0.%desc: PowerNow! K8
dev.powernow.0.%driver: powernow
dev.powernow.0.%parent: cpu0
dev.powernow.0.freq_settings: 1900/50000 1800/45492 1000/20378
dev.powernow.1.%desc: PowerNow! K8
dev.powernow.1.%driver: powernow
dev.powernow.1.%parent: cpu1
dev.powernow.1.freq_settings: 1900/50000 1800/45492 1000/20378


2. eCS A780GM-A (V1.0) (on 780g chipset) and AMD Phenom X4 9600 be
in logs after systemboot isn't any "powernow*"

"dev.cpu.0.freq_levels: 2288/-1 2002/-1 1716/-1 1430/-1 1144/-1 858/-1
572/-1 286/-1" looks strange....
and powerd -v hangs the system. And reset don't reboot the system. 8-(   )
Only full power off can help.

sysctl dev.powernow
sysctl: unknown oid 'dev.powernow'


What should I do or how can I help to make powernow working on AMD Phenom?
