Hi everybody,
Since 2.6.18-rc1, up to and including -rc3, cpufreq has died on me. It
worked fine in 2.6.16.9.
The whole cpufreq hierarchy in /sys/ is missing, nothing is reported during
bootup mentioning 'cpufreq', and when I build with all the cpufreq stuff
configured as modules, I see this:
$ lsmod

# modprobe p4_clockmod
FATAL: Error inserting p4_clockmod
(/lib/modules/2.6.18-rc3/kernel/arch/i386/kernel/cpu/cpufreq/p4-clockmod.ko):
Device or resource busy
dmesg is silent on why this is. I've grepped the files in the cpufreq
directory, but none of them contain EBUSY.
Under 2.6.16.9, this was logged at startup:

Please let me know how I can help solve this problem. Zwane, you are welcome

Kind regards,
