In fact, I want to debug the modules against "/boot/vmlinuz". Not the "bo=
ot/xen.gz"
When XEN installing with ISO, it first load xen.gz,then load vmlinuz,load=
 my driver to check disk.
It hanged at "Checking for existing products...". This is my scsi driver =
problem.

LABEL install
	KERNEL mboot.c32
	APPEND /boot/xen.gz dom0_mem=3D1024M com1=3D115200,8n1 console=3Dcom1,vg=
a --- /boot/vmlinuz xencons=3Dhvc console=3DttyS0,115200 extramodules=3Dm=
y_scsi --- /install.img

I got vmlinuz's kernel source from XS5.6 source ISO image. It already inc=
lude kdb patch.
But it disable XEN to ue kdb.  I can need build xen.gdb to debug vmlinuz?=
 I'm a newbie for XEN.
Any suggestion is appreciated.  Thanks!
