Hmm, looks like setting up the local APIC is the problem. I didn't
actually change anything in that department, so I wouldn't know what
causes it. If you can verify that it didn't happen before my IO-APIC
changes I can try to look into it, but I don't have a recent QEMU
around, so it's hard for me to tell. Also this looks to be rather "old"
as it still sets up MSIs before setting up the local APIC, which
shouldn't be the case anymore.

Michael
