Subject: acpi_cpufreq/cpufreq_stats: "warning: sysfs group ... not found"

Hello everybody!

My notebook is using acpi_cpufreq and cpufreq_stats, with, but the 
same happened for 2.6.26 (and IIRC 2.6.25 and earlier).

I have a script that uses the /sys/ files to show some information.
If I "rmmod acpi_cpufreq" and "modprobe acpi_cpufreq", followed by "rmmod 
cpufreq_stats" (because there's no directory "stats" below /sys/.../cpufreq), 
I get this warning.

The calltrace shows
	? mutex_unlock
