kdump kernel hangs on 2-way AMD Opteron Intellistation

Hi,

We have been using RT kernel as the kdump kernel for most of our work.
This was working fine on 2.6.21.4-rt10 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?
