Although this doesn't happen when *not* using bounce buffers, clearing the pointer to the DMA page after unmapping it fixes the problem. http://marc.info/?t=120861317000005&r=2&w=2 Signed-off-by: Alexey Dobriyan Signed-off-by: Jay Cliburn Signed-off-by: Jeff Garzik --- drivers/net/atlx/atl1.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/net/atlx') diff --git a/drivers/net/atlx/atl1.c b/drivers/net/atlx/atl1.c index 9c2394d4942..79325c4fb54 100644 --- a/drivers/net/atlx/atl1.c +++ b/drivers/net/atlx/atl1.c @@ -2023,6 +2023,7 @@ rrd_ok: /* Good Receive */ pci_unmap_page(adapter->pdev, buffer_info->dma, buffer_info->length, PCI_DMA_FROMDEVICE); + buffer_info->dma = 0; skb = buffer_info->skb; length = le16_to_cpu(rrd->xsz.xsum_sz.pkt_size); -- cgit v1.2.3
