panics with netbsd-INSTALL_XEN3_U

["Dick Davies" <rasputnik%gmail.com@localhost>]

Hi ,

I'm new to xen so hopefully someone can spot something obviously wrong here.

dom0 is xen-3.0.2 on ubuntu breezy, and I've got a debian sarge domU
working fine.

I've tried to boot netbsd-current as domU, following

  http://wiki.xensource.com/xenwiki/NetBSDdomU

I'm  using the latest netbsd-daily kernel from:

  
ftp://ftp.netbsd.org/pub/NetBSD-daily/netbsd-3/200604210000Z/i386/binary/kernel/netbsd-INSTALL_XEN3_U.gz

here's my /etc/xen/netbsd

----------------------------------------------
kernel = "/boot/netbsd-INSTALL_XEN3_U.gz"
memory = 128
name = "netbsd3"
# since linux has no /dev/wd0a, you need to give it as hex (or mknod)
disk = ['phy:/dev/domus/netbsd,0x3,w']

dhcp = "dhcp"
vif = ['mac=00:12:3e:bb:aa:00']

----------------------------------------------

(/dev/domus/netbsd is an LVM logical volume - the installer shows it
an xbd0 and the
size looks correct. The installer gets as far as newfs
(past the 'invalid signature' disklabel error),
and then the kernel panics in pmap.c (see below).

 /var/log/xend.log shows nothing, and xen itself seems ok.

Anything I can do about it?
Thanks.
