[Xen-users] Xen 4.5.x / master ACPI failures

I have been trying to get Xen to work for me on a Lenovo T430 laptop
for a few days now and I'm hoping someone had some better suggestions
to try. I know it should work because I actually have two of these
machines. They are identical machines except for the BIOS version
(UEFI really). The one where everything is working is running 2.05 of
Lenovo's BIOS while the one that is failing is 2.68. Unfortunately
Lenovo prevents you from reverting versions. Both machines are able to
successfully boot Ubuntu 15.04 where everything related to EFI appears
to work correctly. I have tried the Ubuntu 15.04 package (Xen 4.5.0)
and I've also built the code from source (using master and the
RELEASE-4.5.1 tag). Here's the output of booting from the 4.5.1 build
(note I had to apply a patch to get it to compile. I got the patch
from the xen-devel mailing list for OCaml dependencies).

When booting on the working T430, I don't see the error about ACPI
RSDP missing and the machine properly sees 4 cores. I figured if I was
able to boot Xen via EFI then things would work a little bit better.
Unfortunately the screen was completely black when I managed this but
I did manage to configure Intel AMT SOL and get output from what
appears to be the dom0 kernel. Unfortunately it too hangs.

At this point the machine is completely hung. I've tried switching to
Xen master but I get no output to the monitor and I get no output over
the SOL so things are actually worse. I plan on bisecting the tree to
find the commit that caused that but have not yet. I'm just looking
for some ideas on what to try.

I've tried in both cases adding acpi=false and acpi=ht but that has not helped.
