I heard that some bios upgrades can fix the problem, but it did not fix it for me so I gues asus did not know and did not care about a bug that truble linux.
What will "acpi=noirq" do?
What is this timer doing?
Linux is a timesharing kernel. It slices time into bits of 1-10 msec (and feeds slots)
to different processes. The timer interrupt signal needs to be routed to the CPU.
This gets done during initialization. The kernel will get interrrupt routing information
from the ACPI tables, from the MP-table or from standard conventional routing. If
you use the boot argument acpi=off, then the kernel will bypass the ACPI tables and
use the MP-table. At least that is my understanding. If you want to know more search
google for "linux acpi" or intel_MP_spec. The latter term will lead to the 1.4 spec which
explains alot about how multi-CPU systems are laid out. Good reading ... The ACPI spec,
on the otherhand is, to me at least, a nightmare.
