Explanation
P7-IH Hub Nest Memory Management Unit (NMMU) had a catastrophic unrecoverable error. The NMMU is disabled thereby providing no further address translation capability for the HFI units. This prevents non-coherent cluster traffic from flowing to/from the Integrated Switch Router (ISR) using HFI0/HFI1 window resources. P7-IH Hub can continue to service coherent Power Bus traffic from octant to octant, non-coherent traffic from the ISR to other octants, as well as provide PCIe I/O Hub functionality as an independent entity.
