kernel 2.6.29 mobo asus P5N32-E SLI trrouble

Hi all

the development kernel 2.6.29.rc3…5.1 from suse repo

gives trouble with this mobo ASUS P5N32-E SLI with Quad core cpu
Bios 1.07 the latest

It assigns a hole lot of irq’s to cpu 0.

to run things in a normal way i have to add the boot parameters pci=noacpi pnpacpi=no

In the bios all params for spectrum set to spread for cpu and pcie and no plug and play os

now the kernel runs fine
all cpu’s are running not only 1 and 3

The hole pc seems more quikc in boot start kde4 use Emesene
all is working as it should.

Editing jpg’s with Gimp all is snappy no waits

Question is acpi in this kernel broken?

It handels things completely different from a 2.6.27 kernel
