Quoted from Linuxquestions

ACPI = Advanced Configuration and Power Interface

APIC = Advanced Programmable Interrupt Controllers

ACPI is the system that controls your dynamic speed fans, the power button behavior, sleep states, ect.

APIC is the replacement for the old PIC chip that used to come imbedded on motherboards that allowed you to setup interrupts for your soundcard, ide controllers, ect.

In general I'd leave the APIC settings alone. It has been some time since I've had a problem related to that.

However, many computers ship with buggy or out of spec. ACPI firmware which can cause any number of wackiness.

You may have a buggy DSDT

I don't mind at all. I've been using Opensuse more lately, and don't stop by as often. The error message is pretty harmless. The kernel tries to find the timer that syncs the IO devices and fails. The reason is that with the latest hardware (motherboards) have moved the timer to a different place. The problem is that the kernel is not yet up-to-date with this change (although the kernel developers are) and fails during the check. The last three kernel sources have this in the TODO section. You can try adding the

Code: Select all

option if it doesn't cause trouble with your USB devices. If so, you can try to override the timer with

Code: Select all

acpi_skip_timer_override

You need to add them to /boot/grub/menu.lst. Open a terminal and run

Code: Select all

gksudo gedit /boot/grub/menu.lst

Then add the boot option to the end of the "kernel" line. Save and reboot. To remove, rerun the last command and remove what you have added.
