You definitely want acpi-cpufreq, not speedstep-centrino... The 'no such device' message usually indicates that upon querying your BIOS ACPI tables, acpi-cpufreq found no valid frequency scaling information, which suggests either freq scaling is disabled in the BIOS or your BIOS has busted ACPI (in which case a newer BIOS for your board, if available, might help). Also, you can boot with the added parameter 'cpufreq.debug=3D7' to get a bit more info spit out in dmesg about what's going on when you try to load acpi-cpufreq. Could give some further insight into what went wrong and/or verify what I suggested above. --=20 Jarod Wilson jwilson@redhat.com --------------enigCEFD67818B25469EA5A625BF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHOGuKtO+bni+75QMRArwBAJoCWCf3DqYv/YCWUNuusy41Th3XMgCggMoZ SL96L0Yxmqqk5808icLf2MA= =4613 -----END PGP SIGNATURE----- --------------enigCEFD67818B25469EA5A625BF-- --===============2125781766== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Cpufreq mailing list Cpufreq@lists.linux.org.uk http://lists.linux.org.uk/mailman/listinfo/cpufreq --===============2125781766==--
