Description of problem: CPU Frequency Scaling is cited as "unsupported" when booting using Dell D600 Laptop. Micro Version-Release number of selected component (if applicable): kernel-2.6.16-1.2133_FC5 kernel-2.6.17-1.2139_FC5 How reproducible: Everytime Steps to Reproduce: 1. Boot laptop with latest kernel and patches. 2. Login as any user Actual results: Dialogue appears to inform that CPU Frequency scaling is not supported. Expected results: CPU Frequency scaling is supported. Additional info: During the boot cycle with 2133 and 2139, the microcode_ctl module fails to load . The /sys/devices/system/cpu/cpu0 directory contains only a "crash_notes" file. (In 2122 it contained CPU frequency details as well as a crash_notes file, but I guess that's another issue). The cpuspeed service quietly fails to start on startup due to the script /etc/rc.d/init.d/cpuspeed checking for the file /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver. When the Gnome CPU Frequency Monitor applet starts, it reports no frequency scaling support.
please attach the output of dmesg.
