Public bug reported:
I can not set the processor speed to its maximum. I have a centrino duo
laptop (hp nc6320 with T2300E cpu)
I can explain that with an example (on cpu1, the same for cpu0):
cat /sys/devices/system/cpu/cpu1/cpufreq/cpuinfo_max_freq
1667000
cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
1333000
echo "1667000" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
1333000 <---this should be 1.6Ghz!!
On installation phase (ubuntu 6.06) while still in live mode, the single
cpu recognised is able to reach maximum speed. I have an ipw3945
wireless card (seems to affect this-(?))
Thanks.
