I have tried enabling the power management stuff on linux-omap3-2.6.34 kernel but didn't work. It gets stuck on suspension and don't return.
Besides that seems that the cpufreq utilities also doesn't work in the default kernel (it appeared an empty directory at: /sys/devices/system/cpu/cpu0/cpufreq).

Cpufreq did worked on linux-omap-pm, but the current reduduction wasn't significant (compared to the total comsumption) when setting down the freq to 250MHz or 125MHz.

The pm branch seems to be very unstable by now. For me almost half of boot tries fail. Think I will have to wait some time to use it definitily.

Indeed I will not use nor wireless nor bluetooth. How do I disable them?


Thanks,
