kdump kernel tried to load modules not included in the kdump initrd?

I have a 2.6.32-131.6.1.el6 kernel, and kexec-tools-2.0.0-145.el6.x86_64
rpm on a cent6 machine.

When i forced a kdump by 'echo c > /proc/sysrq-trigger',
the kdump kernel panicked during the boot. Surprisingly,
it tried to load lustre modules that should not be part of
the initrd and panicked!

The syslog showed the --initrd specified a kdump.img
when kdump was started. I dumped out the kdump.img
(with zcat) and verified that no lustre module was included
in the initrd image.

So, how did this have happened?
