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): kernel-2.6.9-11.EL How reproducible: Always Steps to Reproduce: 1. Boot uni-processor kernel-2.6.9-11.EL (without acpi=off) 2. 3. 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.
