Key observation during this experiment was that when I turn off acpi interrupt handling (acpi=off), crash has worked on RHEL 5 update 5. I have captured output of lspci and cpuinfo  below for reference.

This can only be done by Red Hat as they are the only ones that know what
patches are in their kernel.  Please file a bugzilla or work with your TAM
to bring attention to the problem at Red Hat.
