After figuring out that I was losing the start of my boot messages and
rebuilding with a bigger dmesg buffer i got the following, all booted
with lapic and apic=debug:
native-vs-xen-fail.diff - 2.6.12.6 native against 2.6.12.6 xen
xen-fail-vs-xen-work.diff - 2.6.12.6 xen against 2.6.12.6 xen with acpi=noirq
dmesg.working-linux.gz - dmesg of 2.6.12.6 native
dmesg.not-working-xen.gz - dmesg of xen3
dmesg.not-working-linux.gz - dmesg of 2.6.12.6 xen
dmesg.working-noirq-xen.gz - dmesg of xen3 with acpi=noirq
dmesg.working-noirq-linux.gz - dmesg of 2.6.12.6 xen with acpi=noirq
