A new catalog and policy guide version which addresses this bug is now available on the official website. If any problems are encountered please open a bug describing the issue selecting the "Red Hat Hardware Certification Program" product. |
Description of problem: x86 has a core limit of 32; on systems with greater than 32 cores some # of cores are not within the kernels control. If these processors are related to cores under the kernels control cpuscaling behavior becomes non-deterministic. Version-Release number of selected component (if applicable): 6.0-4 How reproducible: Random, if the core threshold break on the 32core limit and/or the BIOS happens to do the right things to the cores not under kernel control cpuscaling may work. Additional info: > 32 core + 32 bit should not be required to pass as this issue is a design limitation of the hardware + RHEL and neither nor v7 can resolve this situation. A kbase should be opened to reflect this reality but it should not be required to be amended to all 32bit certifications.
