[Crash-utility] crash-4.0-4.3 and linux-2.6.22.1-20.fc7

Using the latest F7 kernel and crash I'm getting the following error: WARNING: cannot read linux_banner string crash: /usr/lib/debug/lib/modules/2.6.22.1-20.fc7/vmlinux and /dev/crash do not match! I've tried both crash and crash -f with no luck. I've search the mailing list and was unable to find any thing talked about this problem... So I'm thinking this may not be a known problem... If it is, please let me know otherwise does anybody have idea what the problem could be? tia, steved.
