If tg3 does not see the correct bits and indexes in the status block, it won't know what to do. In this case, it doesn't see the link change bit in status block (I suspect), so it is not acknowledging and clearing the link change event.

RC stands for what? Root Complex? I don't know what an RC driver does. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
