Dear all,
The cpufreq modules have been distributed in Centos. But recently,
I met a problem when I tried to test the power-related applications.
The module can not be modprobed in kernel notwithstanding releated
with Centos distribution.
The messgae thrown out is:
------------- dump of screen ------------
# modprobe p4-clockmod.ko
FATAL: Module p4_clockmod.ko not found
--------------------------------------------------
However, the module is there. If I search the kernel path:
------------------ dump of screen ----------------------
# ls /lib/modules/`uname -r`/kernel/arch/*/kernel/cpu/cpufreq
acpi-cpufreq.ko
# find /lib/modules/ -name "*cpufreq*"
