Choose One: CpuSpeed or working ipw2200

[sonnik]

The laptop is a HP DV1500SE. Centrino branding / Pentium M 1.6 GHz, ipw2200.

The kernel that comes with FC6 (kernel-2.6.18-1.2798) works well for me. I'm able to get my ipw2200 device working with wpa_supplicant without issue. However, I can't seem to seem to get the processor to throttle back from 1.6 GHz. This may be related to the problem in this thread.

So, I build a custom kernel - making sure to enable all the right CPU options, SpeedStep, etc. The new kernel fixes my processor CPU speed issue. However, now I can't get my ipw2200 to associate.

The driver loads, the firmware loads, it scans and sees some nearby APs including my own. wpa_supplicant will also see the AP, but it doesn't seem the cryptographic parts seem to want to talk like they should. It just won't 'associate'.

Boot back to stock kernel, ipw2200 works, wpa_supplicant works, I can browse the web, etc.

I've tried building the ipw2200/ieee80211/wpa_supplicant packages from scratch. Same impact.

This is leading me to believe I have overlooked some obscure setting in the custom Kernel compile - but I've checked everything again. I'm just shy of starting from scratch and trying a new kernel build.

You need to install the 686 kernel, it appears that the fc-6 installer always installs the 586 kernel.

Not sure I follow... if the stock kernel is working as is, and a custom kernel (built to my specified target) doesn't work - why would the 686 RPM package work better?

Or are you saying the i686 package will enable CpuSpeed?

When I upgraded to FC6 my Centrino based hp laptop (dv4000) was locked
at the fastest speed.

After the change to the 686 kernel rpm the speed stepping stuff worked.

Cool, I'll give it a shot tonight.

The i686 kernel did fix the CPU Throttling issue. Though, I did still have wireless issues. (Still perplexed as to why it worked with the i386 kernel).

However, at this point - since I was able to verify that it was working with all but one module - I felt compelled to temporarily rename all the /lib/modules/[version] diretories and force a reinstall of the package.

Since the only difference between the i386/i686 version file name is the architecture nomeclature at the end, the i686 wants to reinstall in the same directory.

After did the rename and install, the wireless issue went away.

However, I'm still having a minor issue with the backlight when the display goes to sleep. I'll mention that in another thread.
