The bad news is that palo 1.9 doesn't necessarily work.  The same
lifimage which boots on nicol (N4000) won't boot on the rp8400.

The problem with missing devices is that there's a conflict (two devices
with the same hw path).  At that point, the PAT device enumeration code
gives up.  I've given Vesa a kernel which should fix this, but of course
palo isn't working.

Can you decode 000000001030b504 (HPMC GR02) and 0x000000001030ae7c (IIA)
into kernel symbols?

It's odd that System Requestor is all Zero here:
System Responder Address     = 0xfffffffffc078000
System Requestor Address     = 0x0000000000000000

Based on previous console output, the target device is the
first CPU "Unknown machine". Sounds like IPI failed?
Or is that perhaps the first attempt to deliver interrupts
from an IO device?
