I'm not quite sure whose fault this one is. However, this code in bnx2.c: if (!get_dma_ops(&pdev->dev)->sync_single_for_cpu) { next_rx_buf = &rxr->rx_buf_ring[ RX_RING_IDX(NEXT_RX_BD(sw_cons))]; prefetch(next_rx_buf->desc); } Looks remarkably fragile: what exactly is it trying to do? The commit that causes the problem: commit a33fa66bcf365ffe5b79d1ae1d3582cc261ae56e Author: Michael Chan <mchan@xxxxxxxxxxxx> Date: Thu May 6 08:58:13 2010 +0000 bnx2: Add prefetches to rx path. Looks fairly innocuous by the description. Should parisc have a get_dma_ops()? We don't need one because our dma ops are per platform not per bus.
