Hello Don,
I was trying to reply you directly but comcast refuses to talk with my email server (they require all mail servers to have a PTR record with a valid reverse DNS entry).
But to answer your question. Yes the patch is included in the kernel tree. See also this comment and the code below it in drivers/acpi/processor_perflib.c : ... /* ignore_ppc: * -1 -> cpufreq low level drivers not initialized -> _PSS, etc. not called yet * ignore _PPC * 0 -> cpufreq low level drivers initialized -> consider _PPC values * 1 -> ignore _PPC totally -> forced by user through boot param */ static int ignore_ppc = -1; module_param(ignore_ppc, int, 0644); MODULE_PARM_DESC(ignore_ppc, "If the frequency of your machine gets wrongly" \ "limited by BIOS, this should help"); ...
which is related to bios_limit. I'm not a developer however and don't understand it ... sorry.
Best Regards, I. Petrov

echo 1 > /sys/module/processor/parameters/ignore_ppc worked well. I need to look into the code to find where it is used to understand a bit more what is going on. It has been since 2006 that I did this kind of stuff, and I had to relearn RPM just to get the patched kernel source code. I did not try the kernel boot parameter because I am still afraid of grub2:-) I also found a command on the internet: watch grep \"cpu MHz\" /proc/cpuinfo which provides a real time view of the current processor speed. Since I wanted the system to be faster more of the time, I changed the up_threshold from 95% to 75%. I can't see that this hurts anything, and the computer spends more time acting faster. I used the command: echo -n 75 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold The old system feels much better now! The other thing I wanted to thank you for was the Comcast comment. I have tried to join other suse lists, always receiving a message that their emails were refused. They sent that notification message to me on this list. Any idea on how to get the other suse sites to have the reverse DNS entry, or is there another way to get through comcast, a company that I hate with a passion! They are part of that top 1% problem in our economy that you may hear about if you watch BBC.
