Troubleshooting article for Intel Xeon 6 nodes where the kernel logs "intel_pstate: CPU model not supported". The CPU Governor and Energy-Performance Policy settings then have no effect, cores idle at minimum clock, and guests see high sync-write latency. The fix is a static maximum-performance power profile in the server BIOS. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
