           Summary: Unhandled IRQ9 during resume from suspend to ram
    Kernel Version: 2.6.17-rc6
            Status: NEW
          Severity: normal

Distribution: 
The system is running Ubuntu Dapper, but the kernel is a vanilla 2.6.17-rc6 with
http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-03-pci/pci-reverse-pci-config-space-restore-order.patch
applied on top of it.

Hardware Environment: 
Mac Mini powered by an Intel Core Duo 1.66 GHz(dual core processor)

Software Environment: 
The Mac mini has no BIOS, it uses EFI to boot OSs. Apple provided the Bootcamp
utility that emulates a BIOS in order for other OSs than MacOS to boot the
beast. This system is installed using BootCamp.

Problem Description:
During the wakeup from a suspend to RAM, there seems to be an unhandled ACPI
interrupt that disables the ACPI interrupt from this point. This prevents ACPI
from working after the resume. I'll attach the part of dmesg that corresponds to
a suspend/resume cycle. The error is in the middle of it.

Steps to reproduce:
1. Put the box to sleep using 's2ram -f -p' (the sky2 network driver must be
unloaded prior to that)
2. Wake up
3. look at dmesg
