Severity: wishlist
Tags: patch
Just adding armel to the architecture list seems to produce a working
package. Please consider the attached patch.
Here's a demo of how it works on my openmoko where I was debugging a
kernel bug:
lindi@ginger:~$ sudo crash /usr/lib/debug/boot/vmlinux-2.6.39-gta02-gta02
