I am currently trying to get Xen to boot on my Lenovo T430 laptop with
BIOS 2.68 and using master results in no output to the screen and the
machine being completely hung (must pull the power cable). I've gone
ahead and bisected it and the resultant commit is:

commit 4824bdfdabebd4042277461cb3cbefa61c624804

  x86: add socket_cpumask

  Maintain socket_cpumask which contains all the HT and core siblings
  in the same socket.

Since I'm not getting any output I'm at a loss how to debug this problem
further. I do have Intel AMT setup with Serial Over LAN working so if its
at all possible to get more info over serial I will do that. I am already booting
Xen with console=vga,com1 com1=115200,amt loglvl=all so not sure what
else to add.
