Hi Ben, The code is a bit tricky. It uses function pointers for the various register read/write methods. For the 5780, I believe it will be assigned a simple writel() and not tg3_write32_tx_mbox(). Can you double check to make sure you have actually added the wmb()? It's probably easiest to just add the wmb() in tg3_xmit_dma_bug() before the tw32_tx_mbox(). - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
