From: Kamenee Arumugam <kamenee.arumugam@xxxxxxxxx> For hfi1, the unsupported request error is not considered a fatal error. When the PCIe advanced error reporting capability (AER) is configured to report unsupported requests as fatal, the system will hang on this error. Set Unsupported Request Error bit in Uncorrectable Error Mask register to disable error reporting to the PCIe root complex. Reviewed-by: Michael J.
