I need some help and am willing to pay for consulting. Please contact me directly if interested. Basically I have u-boot running and it will load a kernel via ethernet (fcc). But once the kernel starts the FCC won't transmit packets bigger than the fifo (192 bytes) - it gets underuns. It seems to receive fine. And once and a while it will crash with a machine check. Or a TEA# error. I've done all the obvious things but no joy. For some reason this one doesn't act like the 8260 or 8248. -brad Brad Parker Heeltoe Consulting +1-781-483-3101 http://www.heeltoe.com
