can't boot into dom0

[Mike Wright <mike.wright@mailinator.com>]

Hi all,

New to this list.

I built xen-4.1.1 successfully and can see that it boots from grub with 
the kernel /xen.gz line.

I'm using the following kernel (3.0.0-rc2):

http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git and its default 
.config file,

which also builds successfully and boots standalone.

When I try to boot it as a dom0 I get a segfault.

There is nothing in any of the logs (probably segfaults very early) and 
I can't even see the tail end of the segfault because the screen blanks 
afterward, even though I specify noreboot on the module "kernel" line.

Here's my boot stanza:

title FedoraXen (4.1.1-3.0.0-rc2)
         root (hd0,0)
         kernel /xen.gz
         module  ### all on one line
           /vmlinuz-3.0.0-rc3
           ro
           root=/dev/mapper/vg_lan51-lv_root
           rd_LVM_LV=vg_lan51/lv_root
           rd_LVM_LV=vg_lan51/lv_swap
           rd_NO_LUKS
           rd_NO_MD
           rd_NO_DM
           LANG=en_US.UTF-8
           SYSFONT=latarcyrheb-sun16
           KEYBOARDTYPE=pc
           KEYTABLE=us
           console=tty0
           xencons=hvc
           console=hvc0
           dom0_mem=752M
           noreboot
         module /initramfs-3.0.0-rc2.img

If anybody can point me in some direction where I can capture additional 
info or give me any pointers I'd be most appreciative.

Thanks,
Mike Wright
