I know it's a long shot, but anyone else hear about this problem? The FAEs explained a little about it having to do with load balancing issues across the SRAM in the part. If the load isn't balanced correctly across the transistors, they apparently allow electrons to escape into the flash, which will toggle the flash state and corrupt the chip. I don't really know much about the physics behind transistors, so I don't know if this explanation makes sense or not.
So now because these guys screwed up, we have to call back cards from LM to reprogram them all. Hopefully we haven't already shipped boxes to the end customer in the middle east.
