------- Comment #3 from [email protected] 2008-05-09 05:13 ------- The p4-clockmod must not be used, take the throttling interface exposed through drivers/acpi/processor_throttling.c
instead.
I hope it finally gets removed from the kernel, here a quote from the cpufreq list a while ago (Subject: Celeron 220):
-----------
DaveJ shut it off in the Fedora kernels a while ago now, and only a few people have even noticed, and most understood that it was for the best...

------- Comment #4 from [email protected] 2008-05-28 06:15 ------- Masaki Chikama: your patch at redhat's bugzilla seems to be the proper fix. Could you submit it to the cpufreq mailing list, please?
@Thomas: this is not p4-clockmod.
