[Xen-devel] Xen-unstable 4.8: HVM domain_crash called from emulate.c:144 RIP: c000:[<000000000000336a>]

[linux@xxxxxxxxxxxxxx]

Hi,

Just tested latest xen-unstable 4.8 (xen_changeset git:d337764),
but one of the latest commits seems to have broken boot of HVM guests
(using qemu-xen) previous build with xen_changeset git:6e908ee worked 
fine.
