[Xen-ia64-devel] IA64 xen-3.3 unstable hanging

[Kayvan Sylvan <kayvan@xxxxxxxxx>]

I have an IA64 systems that I had recently booted with xen-3.3-unstable.

Due to circumstances beyond my control, I had to re-install the OS and start
from scratch.

Now, trying to boot it, I see the following on the serial console (and then the 
system hangs).

I think I have all the right SCSI drivers and LVM bits in the linux-2.6.18-xen 
and initrd.

Any ideas for how I can debug this?

ELILO boot: xen33
Uncompressing Linux... done
Loading file initrd-2.6.18.8-xen.img...done
Loading file vmlinuz-2.6.18.8-xen...done
