SubjectRe: repeatable, hard lockup on boot in linux-2.6.0-test4 (more details)

I have similar issue with:
floppy_init()
floppy_grab_irq_and_dma()
fd_request_irq()
request_irq()

floppy_hardint()
...
floppy_hardint()

This causes interrupt storm, hanging the machine on bootup. Booting with
pci=noacpi fixes this. So, I'm assuming acpi pci irq routing problem.
This is irq 6, which ACPI is disabling. Perhaps disabling leaves it in
a bogus state?

thanks,
