Quite a way on now...

I'm reassigning this to the itanium-smp 2.6 kernel in sarge, as that's
the kernel I've finally found the time to debug. All of the ia64
kernels in sarge fail to boot on the SMP HP i2000 workstation I have.
The machine used to be caballero.d.o; I don't know if it's a standard
machine or not, as I don't know much about the history of the machine.

What I _have_ found by trial and error with printk is that the lockup
I'm seeing (in 2.6.8 at least, 2.4.27 may be different) is somewhere
in (or under) ia64_mca_late_init(). By simply adding an early return
from that function (before the #ifdef CONFIG_ACPI block), I can make
the kernel boot fine. I don't know very much about
ia64_mca_late_init() - I'm assuming/hoping it's nothing to do with
Micro Channel Architecture!
