[Xen-devel] Linux 3.14-rc0 + Merge branch 'akpm' (incoming from Andrew - Mon Jan 27) + Xen + i386 dom0 = BOOM



If I boot a kernel that is built on
commit 1b17366d695c8ab03f98d0155357e97a427e1dce
Merge: d12de1e 7179ba5
Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
Date:   Mon Jan 27 21:11:26 2014 -0800

    Merge branch 'next' of 
git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

it boots .

But if I boot with

commit 54c0a4b46150db1571d955d598cd342c9f1d9657
Merge: 1b17366 c2218e2

    Merge branch 'akpm' (incoming from Andrew)

it blows up.

Here is the juicy bit (attached is the full serial log)
