hi all

the second posting went wrong due tot gmail problem (network)

this is /proc/interrupts

did the following run with full acpi

           CPU0       CPU1       CPU2       CPU3

then  run with no acpi

in both cases irq-balancer is running

see the difference in  IO-APIC-edge      i8042


This is a raid 0 system
in the acpi run   irq 22 23 is the raid array

and in the no acpi  run  irq 5 7 is the raid array

all togethher  the no acpi run gives a more equal load on the 4 cpu's

as the acpi run gives 0 60 to 90 % load on cpu 0   the other cpu's not
more then 4 to 10 percent with intervals

hope this gives you more info in what i mean
2.6.27 kernels  acted more like the no acpi setting.
and no warning on the acpi tables in the bios
