The init script did load cpufreq modules and governors, all of that is supposed to be done by the kernel, what governor is used (it will autoload when requested) in the other hand is also not a task for init scripts. quote from the FM. "2.2 Governor ------------ On all other cpufreq implementations, these boundaries still need to be set. Then, a "governor" must be selected. Such a "governor" decides what speed the processor shall run within the boundaries. One such "governor" is the "userspace" governor. This one allows the user - or a yet-to-implement userspace program - to decide what specific speed the processor shall run at." That being said, I think I can see your problem here.. does your log contains ACPI info like [ 3.048788] ACPI: Requesting acpi_cpufreq but your system has no acpi_cpufreq loaded or working ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

[ 3.048788] ACPI: Requesting acpi_cpufreq
but your system has no acpi_cpufreq loaded or working ?
As you probably can figure out from this, the kernel requesting acpi_cpufreq module but not getting loaded properly, has nothing to do with pm-utils, init scripts etc. It has to do either with the kernel of udev. the init script not been there anymore just exposes a bug somewhere else. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Does creating your initrd with dracut (dracut -f) makes the issue disappear for you ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
