Thanks a lot tredegar for your response.
Which linux flavor are you working on?
My Ubuntu 9.04 is from a live-cd downloaded and installed through WUBI from winxp.
My /usr/src does not have a "linux-source-" directory like that of yours.
Code:
GeorgeOfTheBush@ubuntu:~$ ls /usr/src
linux-headers-2.6.28-11 linux-headers-2.6.28-13
linux-headers-2.6.28-11-generic linux-headers-2.6.28-13-generic
There is no "cpufreq" directory in /lib/modules.
Code:
GeorgeOfTheBush@ubuntu:~$ ls -l /lib/modules/2.6.28-13-generic/kernel/drivers/c
char/ clocksource/ crypto/
There is no "cpufreq_stats.c".
Code:
GeorgeOfTheBush@ubuntu:~$ ls /usr/src/linux-headers-2.6.28-13-generic/drivers/cpufreq/
Kconfig Makefile
Also found this info from
http://aldeby.org/blog/index.php/lin...ervolting.html - "It appears that with Ubuntu Jaunty 9.04 the ACPI stuff is now in the kernel rather than in a module which requires you to patch and build the kernel sources."
I am not sure about how I could fix the problem?
