[indiana-discuss] b111a: Power Management and nwam-issue ?

[Detlef Drewanz@Sun.COM]

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).
