-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
It seems that any kernel on my Dell Inspiron 5100 after 2.6.15.6 (including 2.6.17-rc5) 'breaks' my cpufreq in that up to and including 2.6.15.6 I can scale between 300MHz-2.4GHz, but after (starting with 2.6.16) I can only scale between 2.1GHz and 2.4GHz.
I've attached the files, sorted by kernel, I assume may be helpful. Let me know if you need any more.
