>Description:
    I run FreeBSD 10 RELEASE/STABLE on Xen 4.1(XCP 1.6).
One is clean installed about 10 RELEASE. and One is updating from a source with 10 STABLE.
Both VM is very unstable, So stalled, crash, panic and so on.
And I tried to build a kernel /wo xencpi and XENHVM. It was crashed at boot time.

>How-To-Repeat:
1. Install 10 RELEASE on new VM.
2. Check out source tree from SVN repository.
3. make -j 4 DESTDIR=/ world, and stalling.

It is very effective using /w NFS.

>Fix:
I done not know.
