Hi
when I enable powerd with default flags (and any other also) the
computer freezes some seconds after powerd is started. It does not
reach login. Nothing in the logs. This is with amd 5000 X2 Am2

When i stick into the same computer a 4600 or 4200 it runs fine and
smooth.

I thought it is MB related and did the same and again the 5000 cpu
freeze, the smaller ones not.

Any idea what I should do?

I use releng_6 amd and i386 same story and cpufreq and acpi is
compiled.

Disable powerd again and boot normally. Try changing the frequency
with "sysctl dev.cpu", etc. and see if any of the levels freeze for
you.

ok, this is what I get

dev.cpu.0.freq_levels: 2600/100000 2400/85596 2200/72544 2000/60778
1800/50237 1000/25535

no need to say but the fan levels obviously are wrong

And now the interesting part I shift to 2400 or any other and
immediately freeze, that from kde konsole

in single user mode I can shift up and down between all speeds and
nothing happens

[Jumping in from the thread started on -stable -
http://lists.freebsd.org/pipermail/freebsd-stable/2007-July/036395.html
- see there for system details]

Same here - in single user mode, even powerd works fine - like it does
with SMP disabled - but no go in multiuser.

I see some similar discussion on stable but I can not match with
everything there because I have the problem only with the athlon 5000
cpu

The CPU difference is interesting - exactly what model is your X2 4600+?
Mine is a stepping F, model 4B, rev BH-F2 ("Energy Efficient" with 65W
TDP).

seems to be the same

but I have better news and seems my first idea was right, the MB is it

I found a tech info on the manufactor's support site telling cpu support
up to 4600+ and found a bios for newer cpus including my 5000+

so I upgraded the bios and my CPU now works with smp + cpufreq + powerd
on both amd64 and i386

Good to hear. Unfortunately my Mobo's BIOS is already up-to-date, the
CPU is officially supported and Cool'n'Quiet works dandy in Windows XP
... =/

my ok msg was too fast, after some time my video starts flickering and stays
so and the PC is freezed up, disabling powerd and works stable

until it freeze cpu frequency shifting is done well

manually I can set all cpu speeds and seems to stay stable on each

must be related to X because I have some servers without X but
cpufreq+smp+powerd running absolutely stable

I found some msgs about the same problem with Gentoo and Debian and people say
the problem is with xorg and changing to xfree solved it for them but I
myself probably will not risk getting into a nightmare after the /usrX11R6
thing

I have no windows but fedora 7 on the same pc and works fine too,
kde's 'kpowersave info dialog' shows fine the cpu frequency shifting
