Subject: booting "nosmp" kernel causing ACPI errors

Hi,

I observed ACPI errors when booting 2.6.35.7 kernel with "nosmp" argument.
dmesg shows a warning message starting with :
WARNING: at mm/page_alloc.c:1981 __alloc_pages_nodemask+0x5b4/0x6d0()
+Hardware name: MS-7519
+Modules linked in:
+Pid: 1, comm: swapper Not tainted 2.6.35.7 #2

This is followed by ACPI error messages and /proc/interrupts show that
interrupts 0-15 are then handled by XT-PIC-XT
instead of IO-APIC-edge and IO-APIC-fasteoi when runing smp kernel.

Here is lspci dump :

I observed the same issue with another machine with also an MSI 
motherboard but using a PCI bridge VIA VT8237/VX700
even when booting with "pci=use_crs" argument.

Attached is diff -ruN file between 2.6.35.7 kernel without and with 
"nosmp" boot argument.
