powerd on Sempron 3400+

Sat Apr 7 16:23:08 UTC 2007

Hi Mark,

I have had the same problem today :)
acpi_ppc works fine with this processor http://www.spa.is.uec.ac.jp/~nfukuda/software/ 
It seems like powerd is using weird mhz combinations. It tried to lower the processor
speed to 100mhz!

When using ACPI_PPC you can even see the percentage of time at which speed
your processor ws running.

hw.acpi.cpu.px_supported: 1800 1466 1200 933 666 533
hw.acpi.cpu.px_usage: 46.03% 1.28% 1.31% 1.23% 1.51% 48.60%

It is sad that acpi_ppc is not yet in ports. Maybe if you report your
experiences to the author, he can attempt to get it into ports.

Thanks,
Evren

Hi Folks,

  I am trying to get powerd working on a sempron 3400+.  powerd -v
shows it reducing the clock speed for a short period, and
then the system either locks up or in once case paniced.
Sometimes the NIC driver is reporting watchdog timeout, but all
else is locked up.   dmesg.boot attached.  This is 6.2-stable
kernel and 6.2-release user land.  Is this expected to work?
Any suggestions on debugging it?

thanks, markd
