Hi,
I am using b111b (Beta for OSOL2009.06) on my Toshiba Tecra M9 Laptop
and facing still some issues with Power Management.
BTW: I upgraded with the update-manager from osol2008.11 through
dev-build 108 to b111b.
1. I had to set in /etc/power.conf
cpupm enable poll-mode
to see powertop displaying the speed-changes between 2001 Mhz and
800 Mhz.
2. Now if I suspend and resume my laptop, the system only runs with
turbo mode (2001 Mhz) and will no longer change the cpu speed. So
after resume I am no longer able to bring the system back into
variable cpu speeds. Is this a know issue. Is there a workaround
available ? Or is it just a wrong display from powertop ? But kstat
-m cpu_info also shows this speed.
3. After resume, I have seen that runnig prstat it shows me initially
this crazy last line:
Total: 78 processes, 209 lwps, load averages: 1533,45, 504,96, 182,88
I have no clue why this load averages after 12 hours suspend are that
high.
Any comments ? To solve 2. is really important. If that will be not
fixed until osol2009.06 comes out, that is for me a really big
showstopper, because I do not want my laptop to run every time at full
speed.
BTW: I upgraded with the update-manager from osol2008.11 through
dev-build 108 to b111b.
