kdump kernel hangs on 2-way AMD Opteron Intellistation

We have been using RT kernel as the kdump kernel for most of our work.
This was working fine on RT kernel. After which, we moved
over to 2.6.24-rt1 RT kernel. Now, the kdump kernel hangs. Attaching the
complete kdump kernel boot log with initcall_debug option passed to the
kdump kernel.

Kernel config is the same as that in the case of 4-way Opteron. Any
ideas on what could be going wrong here?
