Mark,
I watched the discussion thread from the week end.
I changed in /etc/power.conf cpupm to
"cpupm enabled poll-mode"
and indeed after doing that the system switched down to 800 Mhz
clocking. I was able to see this with kstat and powertop. Good !
Then I suspended my Toshiba M9 Laptop and resumed this morning.
Interestingly this starts in "prstat" with load average of 154 (!) I
don't know why this load is so high in suspend mode ? But what' more
happening is that now again that powertop (and kstat) shows always
2001 Mhz used. So it looks like that after a suspend/resume the power
management is no longer working correctly. I was then not able to
bring this power management to work again. I had to reboot to come
again down to 800 Mhz (and a low noise system).
What does mpstat tell you? Possibly a manifestation of:

Hi,
with b111a now I can boot again my Toshiba M9.
1.I discoverred that Power Management seems no longer to work.
(The fan is blowing like hell and "kstat -m cpu_info" shows in
currentClock_Hz 2001000000
but
supported_frequencies_Hz
800000000:1200000000:1600000000:2000000000:2001000000
New Bug with b111a ?
The cpu_info kstat might be a little deceiving now that the power
aware dispatcher has integrated. Try running /usr/bin/powertop. It
might be more informative.

2. I also have the impression that the boot up is much more disk-io
intensiv and takes much more time (can't identify yet directly)
3. Also: After the boot I see dhcpagent/1 consuming 50 % CPU (looks
like 1 core) and the nwam applet will not show up in the gnome
panel. I first have to "kill -9" the dhcpagent, then the nwam applet
comes up and the cpu consuming goes away.
Any comments ? Anyone else seeing this too.
Thanks
Detlef
