shown by the file extension .aml (ACPI machine language). If this is the case,
continue with step 3.
2 If the file extension of the downloaded table is .asl (ACPI source language),
compile it with iasl (package pmtools). Enter the command iasl -sa
file.asl.
3 Copy the file DSDT.aml to any location (/etc/DSDT.aml is recommended).
Edit /etc/sysconfig/kernel and adapt the path to the DSDT file accord-
ingly. Start mkinitrd (package mkinitrd). Whenever you install the kernel
and use mkinitrd to create an initrd, the modified DSDT is integrated and
loaded when the system is booted.
15.4.2 CPU Frequency Does Not Work
Refer to the kernel sources (kernel-source) to see if your processor is supported.
You may need a special kernel module or module option to activate CPU frequency
control. This information is available in /usr/src/linux/Documentation/
cpu-freq/*.
15.4.3 Suspend and Standby Do Not Work
ACPI systems may have problems with suspend and standby due to a faulty DSDT
implementation (BIOS). If this is the case, update the BIOS.
When the system tries to unload faulty modules, the system is arrested or the suspend
event is not triggered. The same can also happen if you do not unload modules or stop
services that prevent a successful suspend. In both cases, try to identify the faulty
module that prevented the sleep mode. The log file /var/log/pm-suspend.log
contains detailed information about what is going on and where possible errors are.
Modify the SUSPEND_MODULES variable in /usr/lib/pm-utils/defaults
to unload problematic modules prior to a suspend or standby.
