static int
dm9000_open(struct net_device *dev)
{
board_info_t *db = (board_info_t *) dev->priv;
PRINTK2("entering dm9000_open\n");
set_irq_type(dev->irq, IRQT_RISING); //添加
if (request_irq(dev->irq, &dm9000_interrupt, IRQF_SHARED, dev->name, dev))
return -EAGAIN;
/* Initialize DM9000 board */
dm9000_reset(db);
dm9000_init_dm9000(dev);
/* Init driver variable */
db->dbug_cnt = 0;
/* set and active a timer process */
init_timer(&db->timer);
db->timer.expires = DM9000_TIMER_WUT;
db->timer.data = (unsigned long) dev;
db->timer.function = &dm9000_timer;
add_timer(&db->timer);
mii_check_media(&db->mii, netif_msg_link(db), 1);
netif_start_queue(dev);
return 0;

解决办法：
dm9000.c中添加set_irq_type(dev->irq, IRQT_RISING);
static int
dm9000_open(struct net_device *dev)
{
board_info_t *db = (board_info_t *) dev->priv;
PRINTK2("entering dm9000_open\n");
set_irq_type(dev->irq, IRQT_RISING); //添加
if (request_irq(dev->irq, &dm9000_interrupt, IRQF_SHARED, dev->name, dev))
return -EAGAIN;
/* Initialize DM9000 board */
dm9000_reset(db);
dm9000_init_dm9000(dev);
/* Init driver variable */
db->dbug_cnt = 0;
/* set and active a timer process */
init_timer(&db->timer);
db->timer.expires = DM9000_TIMER_WUT;
db->timer.data = (unsigned long) dev;
db->timer.function = &dm9000_timer;
add_timer(&db->timer);
mii_check_media(&db->mii, netif_msg_link(db), 1);
netif_start_queue(dev);
return 0;
