/sbin/init get "Segmentation Fault" while FreeBSD 8.0-RELEASE-p2 i386 =
Xen DomU is booting.
Xen Dom0 info:

The Segmentation Fault issue appears when the DomU is configures with =
option 'vcpus' value =3D>2.
In case 'vcpus' undefined, the DomU boot fine with single CPU.
Here is FreeBSD Domu console boot messages (when vcpus =3D "2"):
