This is great news!  :-)

Could you share those minor changes?

P.S. I moved this conversation to fedora-xen since we''re trying to
consolidate discussion around fedora-xen-ia64 on that list.

The configuration change is just copying xen.gz from /boot to
/boot/efi/efi/redhat.

The kernel panic happens in initrd when mounting root devices. There is no real
initrd change. My build is working. I''m using mkinitrd-5.0.32-1 and
cpio-2.6-11.2.1. Could you check yours? I think actually cpio causes the issue
since kernel panic goes away after I re-archieve your initrd with my cpio.

Thanks.

Ah, okay, thanks.

I''m using cpio-2.6-17 and mkinitrd-5.0.40-1 now.  I''m not sure
what
I was using when the rpms were made, since I''ve updated recently!

However I found that my panic was due to a mistake I made in
elilo.conf.  I can boot dom0 now that I fixed that.  Here is what I''m
using:

image=vmlinuz-2.6.16-1.2211_FC6.agriffisxen0
        label=xen-2.6.16-1.2211_FC6.agriffis
        vmm=xen.gz-2.6.16-1.2211_FC6.agriffis
        initrd=initrd-2.6.16-1.2211_FC6.agriffisxen0.img
        root=/dev/VolGroup00/LogVol00
        read-only
        append="sched=bvt sync_console -- rhgb quiet xencons=ttyS8
console=ttyS8 root=/dev/VolGroup00/LogVol00"

Hmmm, well hopefully this won''t continue to be a problem.  The initrd
directly from the rpm is working here...
