I've got a fresh F-10 install on a Core 2 Quad machine. While looking through dmesg output for a clue to another problem, I noticed this: p4-clockmod: Warning: EST-capable CPU detected. The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible. p4-clockmod: Unknown p4-clockmod-capable CPU. Please send an e-mail to <cpufreq@xxxxxxxxxxxxxxx> (repeated 3 more times) First I wondered why I was getting a cpufreq module loaded on a desktop machine. I guess I want to do something if the CPU temperature gets too high, but it doesn't look like the default configuration handles that case, does it? Anyhow, I edited /etc/sysconfig/cpuspeed to explicitly say: DRIVER=acpi-cpufreq On the next reboot, I had the same complaint in dmesg. On a hunch, I checked the output of lsmod; p4-clockmod isn't listed. It does exist as a module here: /lib/modules/2.6.27.5-117.fc10.x86_64/kernel/arch/x86/kernel/cpu/cpufreq/p4-clockmod.ko So is it also compiled in? -- Jerry James http://loganjerry.googlepages.com/ -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
