phc module not working in PPA - since Kernel 2.6.32-23

Post by marcschh » Thu 5. Aug 2010, 13:29

anyone who has the same trouble?
or anyone who knows how to get it working/ find the failure?

-------------
I use the PPA
https://launchpad.net/~linux-phc

and with the Kernels 2.6.32-23-generic-phc and 2.6.32-24-generic-phc the phc_controls does not exists anymore.
But when I use the old 2.6.32-22-generic-phc, the phc_controls exists and safes a lot of energy on my laptop

xxxx@yyyyy ~ % cat /sys/devices/system/cpu/cpu1/cpufreq/phc_controls
cat: /sys/devices/system/cpu/cpu1/cpufreq/phc_controls: No such file or directory
xxxx@yyyyy ~ % dmesg | grep phc :(
