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().
