I use the cpufreq module and powernowd for frequency scaling. It seems to work well except it crashes on shutdown:
Code:
localhost powernowd: PowerNow Daemon Exiting.
localhost powernowd: powernowd shutdown succeeded
localhost cpufreq: Unloading cpufreq modules :
localhost cpufreq: failed
localhost cpufreq:
localhost cpufreq: /etc/rc0.d/K35cpufreq: line 199: 3100 Killed rmmod $MODULE 2>/dev/null

Halting system
Synchronizing SCSI cache for disk sda:
And then it freezes at that point, and does not power-down (it does power-down with cpufreq and powernowd disabled).
Any ideas? Thanks.
specs:
-- Mandrake LE2003
-- kernel 2.6.11-12mdk
-- powernowd version 0.95
-- AMD64 3800+
