[c-nsp] Sup720 crashing at RP boot - HW revision dependent ?

[Tassos Chatzithomaoglou]

Marcus, are you using the latest rommon in the SP (8.5(3)) and RP (12.2(17r)SX5)?

6500#remote command switch sh ver | i ROM:
ROM: System Bootstrap, Version 8.5(3)

6500#sh ver | i ROM:
ROM: System Bootstrap, Version 12.2(17r)SX5, RELEASE SOFTWARE (fc1)
