Problems with PHC and Kernel 3.0 ,no such device or directoy

Post by Ratpoison 82 » Thu 29. Dec 2011, 03:54

Hi Everybody ,
iam new here , here's a little introduction of myself . My Name ist Andy , i am 29 Years old and from Germany .
And here's my problem , I use Lubuntu 11.10 with the PHC Kernel 3.0 . I also installed the phc-intel-pack-rev3 , i blacklistet the acpi_cpufreq and cpufreq_stats modules , and added phc-intel in /etc/modules .
I restarted , and asked cat /sys/devices/system/cpu/cpu0/cpufreq/phc_controls , but it alway gave me " No such Device or directory " .
But I dont't know why ?
If I go in the cpufreq directory , i can see the file phc-controls an other phc files , but I can't open them .
I had PHC working just fine under Ubuntu 11.04 with Kernel 2.6.38 , but with the 3.0 Linux Kernel , it doesn't work on my Machine ( IBM Thinkpad with Pentium M ) .

It would be nice if you could help me .

If you have a Pentium M, phc doesn't work on Kernel 3.
