I had something similar happen with a Supermicro X7SBA motherboard with IPMI. When we sent over a new kernel, we lost contact with the BMC shortly after networking was started. I think it was somewhere in 2.6.31, which sounds consistent with your experience. Rolling back to the previous kernel fixed the problem. I opened a case with Supermicro's tech support, which didn't get very far. One thing I learned was that Supermicro has an IPMI utility that runs in Linux, which lets you fetch data from the BMC or upgrade its firmware. We've seen other weird behavior with Supermicro's IPMI implementations - they block ports 623 and 644, even if you don't have the BMC controller installed in the slot, and my favorite bug, on motherboards that have a dedicated Ethernet interface for IPMI, if that interface is not plugged into a switch at bootup, the IPMI connection silently moves over to one of the regular motherboard Ethernet ports, and stays there, across reboots, until you hard power-off the computer. ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
