Hi!
(Added myself to CC, because I'm not subscribed)
with linux-next snapshot 20080604 my Laptop morphes into sitting duck and I think this is due to this:
dmesg | grep "GSI 11" ACPI: PCI Interrupt 0000:00:11.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11 ACPI: PCI Interrupt 0000:00:11.1[B] -> Link [LNKB] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11 ACPI: PCI Interrupt 0000:00:02.0[A] -> Link [LNKG] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11 ACPI: PCI Interrupt 0000:00:06.0[A] -> Link [LNKH] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11 ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKD] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11 ACPI: PCI Interrupt 0000:02:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 ERROR: Unable to locate IOAPIC for GSI 11

AFAIK this chipset doesnt provide a usable IO-APIC, but older Kernels upto 2.6.25.4 didn't have a problem with this. Will try 2.6.26-rc5 today..
If you want some other infos (config etc.) just let me know.
