Message-ID:  <4AC7578A.4060400@winnipeg.nl>

I'm trying to get FreeBSD CURRENT working under Xen 3.4.1 using the 
Gentoo dom0 kernel 2.6.29.6
I downloaded and compiled the 8.0 svn version revision 197720 from 
http://svn.freebsd.org/base/head with the KERNCONF=XEN option but when 
I'm starting my domU I'm getting the following panic:

I'm getting the same panic when I add only 1 cpu.
I'm using the following boot line for pygrub:
kernel /boot/kernel/kernel 
vfs.root.mountfrom=ufs:xbd0,kern.hz=100,kern.smp.disabled=1,boot_verbose=1,boot_single=1
I've tried it with and without the kern.smp.disabled option

Does anyone have any ideas about what's going wrong?
