cheers, am i correct in thinking your are running a smp kernel
also the driver you need for cpuspeed is park of the kernel and not p4-clockmod. so you can comment out the driver directive. oh and using a non smp kernel helps aswell. here's a quick test
do a
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
should print 1599960 or there abouts
this is the current frequency that the cpu is running at 1.5Ghz
now get the pid of cpuspeed
Code:
ps -u root | grep cpu
now we ramp up the frequency of the cpu to full speed
Code:
kill -s SIGUSR1 (pid of cpuspeed)
and check the frequency of the cpu
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
should be about 3066590
to bring it back down to dynamic scaling
run
Code:
kill -s SIGHUP (pid of cpuspeed)
hope this helps
Cheers ws
