We also had this problem with Supermicro boards and IPMI cards in a large
scale. Finally we found a solution by upgrading the firmware of the NICs which are
actually from Intel.
You might want to ask the vendor or you trader to get a beta version
which is more recent than the public available one for both -  the IPMI
cards and the NICs.
Unfortunately, this problem occurs occasionally which makes testing
difficult. We took a supset of nodes, played the new NIC firmware onto
it and waited a long time.  

Good luck,
