Are all interrupts supposed to be handled by CPU0 on x86_64, or is
something amiss? I'm getting the following on Mandrake Corporate Server
2.1:

I see this behavior on systems using either the MSI or Tyan dual-opteron
boards. I also see it on RedHat's preview x86_64 distribution (kernel
version 2.4.20-9.2).
I'm still trying to get 2.5.69 to boot correctly, so I don't have
results there yet. On RedHat it hangs after "Booting the kernel..."
(and yes, I have CONFIG_VT, and CONFIG_VT_CONSOLE on). Any ideas?
