Few things i need from you. First is output of cpufreq-info. Then
all the steps you did to reproduce above? Removed any other cpus?

I am not able to find next-20130326 tag in my repo, only have 23 and 28.
Can you debug it a bit to find exact line of code causing this issue using
objdump?

HINT: Documentation/BUG-HUNTING..

Give me line numbers of both of these functions: __cpufreq_governor() and
__cpufreq_remove_dev().
