Martin, et al,
I also believe this is a problem.
I just haven't seen it because I'm always using serial console.
This problem might also exist on x86 Foster CPU as well.
The new x86 CPU also uses IO-xAPIC and Local xAPIC.
I don't have access to a physical memory map of such a box
to confirm it though.
I don't believe this is a problem on HP parisc (also uses
IO-SAPIC) because of how PCI address routing works.
