 I can confirm that the problem occurs using 8.0-RELEASE on a CentOS
 5.4 x64 host.
 
 I successfully built my domU using the steps on this site ->
 http://www.ita.com.ua/eng/articles.htm?id=34 and the default XEN
 kernel configuration with no changes.
 
 Here is my domU configuration:
 
 kernel = "/var/lib/xen/images/freebsd8dev.kernel"
 memory = 256
 name = "freebsd8devp"
 vif = ['']
 disk = ['file:/var/lib/xen/images/freebsd8dev.img,hda1,w']
 extra = "boot_verbose=1"
 extra += ",vfs.root.mountfrom=ufs:/dev/ad0s1a"
 extra += ",kern.hz=100"
 pae=1
 vnc=1
 
 I reproduced the problem by running a kernel rebuild inside the domU
 until this point during make:
