I'm having Sporadic connectivity with IPoIB using the WinIB stack on MLX Infinihost II Ex HCAs and Cisco 7000P switches with integrated SM (on the switch). Is there a specific power on sequence I should be using or other considerations?<BR>
<BR>
Also, are there any compatibility issues with using OFED gen2 and WinIB gen1 stacks? I have been having nothing but headaches with IPoIB and SRP.<BR>
<BR>
Please help. Thank you.<BR>

The WHQL drivers are approximately build 614, and I know the IBAL interface has new functions and a new version number in the current build. There is absolutely nothing to tell Windows Update that drivers for PnP hardware id “IBA\IPoIB” in version 614 of the IB stack will not work on a stack looking for say the 758 build of the PnP hardware id “IBA\IPoIB”.</FONT></FONT><BR>
