I think what you have here is a bad SSA card. Really what your going to need to do at this point is call IBM hardware support (assuming your server is under warranty) and explain to them the problem. You will need to provide them with your machine type/model or serial number. To get machine serial number, you can type prtconf | pg and near the top of the output you'll find the system model, and serial number. Once they determine the hardware problem, they will dispatch a hardware tech out to replace your failing device.

good luck.
