[Crash-utility] crash failed on vmcore created by kdump at an IA64

Hi, I saved off a vmcore from a kexec'ed crashkernel at an IA64 Altix. When i tried to run crash (4.0-3.5) on the vmcore, it failed. Is there a known issue? Thanks, - jay % crash System.map* vmlinuz-2.6.18-kdump vmcore crash 4.0-3.5 Copyright (C) 2002, 2003, 2004, 2005, 2006 Red Hat, Inc.
