I have just upgraded my notebook BIOS, and speedstep-centrino stopped loading, now I get a "no such device" error. I also can't load acpi-cpufreq. It may be that the BIOS itself is broken, but perhaps it's a "valid" BIOS condition that Linux can't yet recognise. I've tried under 2.6.18-rc4, 2.6.17.13 and the Ubuntu kernels.

Ben, I don't see _PSS _PCT objects in ACPI dump that are required for the driver to support speedstep. For some reason BIOS stopped exporting those information. Can you check whether this new BIOS has some option to enable this feature? Something that may say Speedstep, Enhanced Speedstep, Enhanced Intel Speedstep (EIST) or something similar? -Venki
Just went into the BIOS and the only CPU related option is to enable or disable dual-core mode. I disabled, and Linux now sees one core, but still no cpufreq. There aren't many places for this option - the bios setup screen is one of those basic drop-down menu ones with only a few options.
Time to send a mail to your BIOS provider. Do you have Windows installed on this system? Can you check whether frequency changes are working over there. If you say it does not work on Windows you may get better attention from the BIOS provider ;-)
As the BIOS here seems to have deleted processor power management, there isn't anything we can do. It would be interesting if you could load the previous BIOS, verify that it works, and attach the dmesg and acpidump from that configuration.

I've loaded the previous bios and cpufreq works again. Attached the dmesg and acipdump from this bios. So it looks like a nasty BIOS bug, thus have sent a case to HP regarding this issue and running the earlier bios for now.
A new F.08 BIOS is available now from the hp.com website, which fixes the speedstep problems on the nx7400. In addition, I've been told that a new BIOS rev is planned for all 2006 model business notebooks, which will fix this problem across the board (including the nc6400). It should be available sometime soon in December.
I have spoken to HP support in Sweden about this problem too. They told me they would escalate it. I'm waiting for feedback and will post it here if and when I get it.
I received a beta BIOS (68ycu.bin) from HP support today. Version F.06, dated 10/25/06. The upgrade worked, and now the cpufreq_ondemand module is loaded. I cannot choose automatic in the Gnome PM applet menu, though. If anybody is interested in logs, command outputs etc from the system, please let me know.
Reply-To: jad.jebara@yahoo.com How is the battery life with the new Bios? Do you know when HP will be releasing the new BIOS? I called them up repeatedly in Canada, and there is no info about the new BIOS version! Thanks!
