--- Comment #1 from Zhang Rui <rui.zhang@intel.com> ---
please make sure your kernel is built with CONFIG_DYNAMIC_DEBUG=y.
please make sure the debugfs is mounted
Then, please run
"echo -n 'file acpi-cpufreq.c +p' > <debugfs>/dynamic_debug/control"
"echo -n 'file cpufreq.c +p' > <debugfs>/dynamic_debug/control"
"echo -n 'file processor_perflib.c +p' > <debugfs>/dynamic_debug/control"
before modprobe the acpicpufreq driver
and attach the dmesg output after it.

please attach the .dat tables using the following script:
#!/bin/bash

TABLE_PATH=/sys/firmware/acpi/tables

for i in $(ls $TABLE_PATH)
do
        if [ -d $TABLE_PATH/$i ]
        then
                continue
        fi
        cat $TABLE_PATH/$i > /tmp/$i.dat
done

for j in $(ls $TABLE_PATH/dynamic)
do
        cat $TABLE_PATH/dynamic/$j > /tmp/$i.dat
done
