Here is init_apic_ldr_phys from 'objdump -d xen-syms-3.4.3-rc4-pre':

I don't quite understand why we have such different addresses. I'm
thinking maybe I built it wrong or something. I built it with debug
set to 'y' in Config.mk, then just did 'make dist', copied the
resultant 'dist' directory to the test machine and ran 'sh
./install.sh' on the target machine, and rebooted with:
title Xen-3.4.3-rc1.dan -- SUSE Linux Enterprise Server 11 -
2.6.27.19-5 (xen).dan
root (hd0,0)
kernel /xen-3.4.3-rc4-pre.gz crashkernel=128M@16M iommu=1

ugh.. long story. It works in the sense that it boots and can run
VMs. My problem is that I'm trying to get the board that our company
makes to work in an HVM guest properly.. *something* is messing with
my board's PCI bar registers and I cannot figure out what it is. I
added printks to all the kernel functions which touch the BAR
registers and to the pciback driver as well, but neither of these is
occurring, so I figured the problem is in qemu, but to test that I
need to be able to compile it. I thought that the easiest path there
would simply to compile the latest stuff, but it panicked early in the
hypervisor so I thought that I'd report it...
thanks,
dan
