This bug entry is created to separately collect information previously handled
in bug 239101.

Taking a secondary CPU offline and online again makes this CPU lose its
/sys/devices/system/cpu/cpu1/cpufreq link.

This will cause kpowersave to show the CPU as deactivated.

The same will happend when the machine goes into suspend2disk and resumes
again.
