 <0>Kernel panic - not syncing: Oops

The system is a HP xw9300 Dual-Opteron workstation with 4 GB RAM, NVIDIA
QuadroFX 3400, LSI Logic 53c1030, System bios v1.21 786B9

The system crashes with a smp kernel because of Bug #160135 (with
and without acpi=off - please see my oopses there). With a uni-processor
kernel it only boots with the kernel argument apci=off. Without
it we get the oops above.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot uni-processor kernel-2.6.9-11.EL (without acpi=off)

Actual Results:  oops

Expected Results:  no kernel panic

Additional info:

Because of this bug and #160135 we currently are only able to use a single
CPU and no ACPI on this workstation.
