I installed NetBSD on a HPNX9420 laptop with a dual core CentrinoT2600/2.16GHzCPU With the Generic kernel both cores revs up to maximum frequency and stays there. This result in high temperatures within a few minutes and the fan is constantly on max speed and noise. I installed estd-0.7 from pkgsrc. When I ran estd for the first time it said it can not guess CPU-scaling technology. Ok, so I built a new kernel where I enabled odcm0 in the conf file. est0 was already enabled. I rebooted and ran estd again. Same message, can not guess CPU-scaling. Now I built a new kernel where I added the following options to the conf file: ENHANCED_SPEEDSTEP, EST_FREQ_USERWRITE and INTEL_ONDEMAND_CLOCKMOD. Rebooted and ran estd again, same result, can not guess CPU-scaling.
This laptop runs pretty cool on other os' including Ubuntu and Windows so clearly THOSE os' are able to modulate the frequency. What are my options here? Are there other configuration options I should compile in? Any other programs out there I can try in order to control cpu frequency? Any help appriciated.
