Obviously not in 2.6.24.1, and I thought that 2.6.24.2 just added the fix for the vmsplice exploit. So unless 2.6.24.3 has been released...?

So we discover the same devices twice? Can this be a reason for the hang?

It hangs when I *don't* add the acpi=noirq option, whereas here it's just adding noise to the dmesg log. (I'm guessing Linux doesn't call pci_legacy_init() when ACPI takes charge of the IRQs.)
