How long of an output should I expect when iommu=debug is enabled?
I've just enabled it and I'm looking at what appears to be an endless
scroll of debug info.

This is all I see for the good 5 minutes at this point. Culminating with:
(XEN)   (XEN) APIC error on CPU0: 40(00)

and a failure to boot.

Note that this is still without no-igfx

I'm attaching the tail end of this log.

Thanks,
Roman.
