Comment 21 for bug 118765

I checked again for frequency scaling and came up with a new theory to the bad generic kernel performance.

"cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors" reveals this:
powersave ondemand userspace conservative performance

When I switch through the governors CPU frequencies are actually scaled. However either max or min are used (I checked scaling_available_frequencies and there are the same frequencies defined as with the 386 kernel, where frequency scaling works fine).

ondemand and performance governor lead to the max frequency used all time and powersave does lead to the min frequency to be used all time. I think userspace resulted in min frequency as well.

My theory for the slow boots is now, that when the kernel boots min frequency is used and as soon as acpid, ... are started max frequency is used. What the reason for all this is, I still can't imagine.
