An Intel customer discovered an issue implementing Intel® Xeon® Processors 5400 series E-0 stepping and BIOS R0091 or Intel® Modular Server BIOS R0047. Approximately one out of three boots will exhibit a non-maskable interrupt (NMI) with one or more of the following characteristics:

  • Immediately following POST, the following error may be seen: NMI detected. System Halted, followed by a system hang.
  • No POST, no video (system hang)
  • System hang with the following POST Code LED indicators: MSB off | off | green | amber LSB
  • In some instances, uncorrectable memory errors may be falsely reported in the system event log (SEL), and DIMM's C1 and D1 may be taken offline.
