I won't be able to answer all your requests at once, but let's start with what
I can already provide:
1) Manually issuing "modprobe acpi-cpufreq" works without any issues or
warnings and the CPU speed directly drops down. So everything works from this
perspective.
2) When removing the processor module (which worked without the -f), and then
reloading it again loads surprisingly the acpi-cpufreq module.
Looking at the dmesg file, I see that the processor is requesting also at the
startup:
[ 2.701809] Write protecting the kernel read-only data: 10240k
[ 2.703396] Freeing unused kernel memory: 244k freed
[ 2.703746] Freeing unused kernel memory: 44k freed
[ 2.746988] ACPI: Requesting acpi_cpufreq
[ 2.763372] thermal LNXTHERM:00: registered as thermal_zone0
[ 2.763378] ACPI: Thermal Zone [THM0] (48 C)
[ 2.771180] usb 1-1.5.5: New USB device found, idVendor=046d, idProduct=c062
[ 2.771186] usb 1-1.5.5: New USB device strings: Mfr=1, Product=2,
SerialNumber=0
[ 2.771191] usb 1-1.5.5: Product: USB Laser Mouse
So it seems that the kernel is doing it's job by requesting the correct
modules, but this is happening at the moment while the initrd is still active
(or the only filesystem available). Checking the initrd, indicates that certain
modules are not present. The initrd only contains the following modules:
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/gpu/drm/i915/i915.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/gpu/drm/drm_kms_helper.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/gpu/drm/drm.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/i2c/algos/i2c-algo-bit.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/scsi/device_handler/scsi_dh_alua.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/scsi/device_handler/scsi_dh_hp_sw.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/scsi/device_handler/scsi_dh_emc.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/scsi/device_handler/scsi_dh_rdac.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/scsi/device_handler/scsi_dh.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/acpi/button.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/acpi/video.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/acpi/fan.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/acpi/processor.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/acpi/thermal.ko
lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/thermal/thermal_sys.ko
In order to work correctly, the initrd should also contain the modules in the
directory lib/modules/3.4.0-rc6-1-desktop/kernel/drivers/cpufreq.
So this seems to be a mkinitrd bug and not a kernel bug.
