Rather than compiling 2.6.17, I compared speedstep-centrino.c from Ubuntu's 2.6.17 kernel package, against the upstream source. Ubuntu have obviously patched it, adding freq/voltage tables for Pentium M Dothan cores (upstream only supports Banias). They've also done this in their 2.6.20 package for Feisty. So I guess my notebook has broken ACPI BIOS, and the frequency scaling has only ever worked because of the linux-phc patches that Ubuntu were applying :( Hopefully they'll at least keep doing that, to save me from having to patch it myself each time. I still don't understand why these patches for the Dothan cores have never made it into mainline... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
