Error inserting acpi_cpufreq no acpi_cpufreq in /lib/modules/2.6.18-1.2747.fc6/kernel/arch/i386/kernel/cpu/cpufreq

[Antonio Olivares]

Dear all,

    When I start the machine, I get to see the message that there was an error inserting
acpi_cpufreq in /lib/modules/2.6.18-1.2747.fc6/kernel/arch/i386/kernel/cpu/cpufreq
It says that there is no acpi-cpufreq.ko, and I looked for it and it is there 

[olivares at localhost cpufreq]$ cd ~
[olivares at localhost ~]$ cd /lib/modules/2.6.18-1.2747.fc6/kernel/arch/i386/kernel/cpu/cpufreq
[olivares at localhost cpufreq]$ ls
acpi-cpufreq.ko  p4-clockmod.ko
[olivares at localhost cpufreq]$ 

Is this a bug?  

Regards,

Antonio
