Wow, registering for Novell's bugzilla is painful. And in the end I get "Access denied" on that bug. Can you give us this information some other way? > Shutting down the network causes an MCA because of an IO TLB error when > a DEC quad 10/100 card is in any slot.

I'm hesitant to make even obviously correct changes to the tulip driver without good evidence, given the incredible variety of buggy hardware out there. This looks to me like another iteration of the shutdown DMA/irq race at first glance. Grant has a patch for it; I'm working on one I consider cleaner. -VAL > > > Signed-off-by: Olaf Hering <[EMAIL PROTECTED]> > > --- > > Andrew: Why is it tp->pdev instead of pdev? > > drivers/net/tulip/tulip_core.c | 1 + > 1 file changed, 1 insertion(+) > > Index: b/drivers/net/tulip/tulip_core.c > =================================================================== > --- a/drivers/net/tulip/tulip_core.c > +++ b/drivers/net/tulip/tulip_core.c > @@ -1798,6 +1798,7 @@ static void __devexit tulip_remove_one ( > return; > > tp = netdev_priv(dev); > + pci_disable_device(tp->pdev); > unregister_netdev(dev); > pci_free_consistent (pdev, > sizeof (struct tulip_rx_desc) * RX_RING_SIZE + - 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
