[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi Konrad,

A new year and a new linux merge window looming, so i thought i would try out 
the "devel/for-linus-3.14" branch.
But dom0 seems to blow up for me .. (without this branch pulled it works ok)

Xen: latest xen-unstable
Linux: latest 3.13-rc7+ with devel/for-linus-3.14 branch pulled on top of it.

The complete serial log is attached.
