Yep, i figured that was my problem.
I copied my vmlinux, which is a 2.6.18-8.el5, to my disk server,
which is a 2.6.16.43-0.5-default.

I would think the OSRELEASE of the CONFIGFILE generated from
'makedumpfile -g CONFIGFILE -x VMLINUX' would be the version
of VMLINUX. Instead, it said: OSRELEASE=2.6.16.43-0.5-default,
which caused 'makedumpfile -i' to complain about:
   CONFIGFILE and VMCORE don't match

I think it is a bug? You would want to ensure the version of
the VMLINUX and VMCORE match.

I love this idea!

Thanks,
