Michael, Peter bounced this email to me after we talked about issues he was having with the rx8620 (HP 16-way ia64, sx1000 chipset) "IOX Core LAN". It sounded like the same problem I tracked down with rx8620 IOX Core LAN in March. Here is the summary : | In May, 2004, tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting | programmed and how to determine what to program into LED_CTRL.

Thanks Grant, I'll chase this down and find a solution to this problem.
