The same situatuation with this configuration:
Host Power Status : Host is currently ON
RMM Status : Intel(R) RMM installed
Device (BMC) Available : Yes
BMC FW Build Time : Nov 14 2011 16:07:45
BMC FW Rev : 01.12
Boot FW Rev : 00.03
SDR Package Version : SDR Package 1.11
Mgmt Engine (ME) FW Rev : 02.09.032.0
Got same issue for all MB from first (S1200BTL) to last S1200BTLR.
All of them (we have more than hundred) BMC stops responfing after from couple minuntes to some hours after boot.
Talking with Intel "specialists" but half of its questions about my problem is:
Could you please also provide us with the following information:
How many system used and how many of them are affected by the issue?
How many times I must answer to them to prove that we have problem!?
