找不到嵌入式驱动版块，发这也差不多吧

CPU：AT91RM9200
Kernel:2.6.17

问题描述：
dm9000静态加入内核编译可以通过，内核起来后可以识别
[root@ktdup5390 /]# ifconfig dm0
dm0 Link encap:Ethernet HWaddr 44:4D:50:00:036
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:26 Base address:0xe300
ping自己可以ping通，但与其他主机ping不通（估计没走硬件，直接从协议站里回去了 ）

配置IP后出现如下问题
[root@ktdup5390 /]# ifconfig dm0 192.168.2.111

dmfe_open: start---------sqq
dev->name is dm0
dev->irq num is 26
request_irq:start
request_irq:setup_irq
setup_irq:start
setup_irq:spin_unlock_irqrestore
BUG: soft lockup detected on CPU#0!

然后就死这了

追进去看了一下，是中断申请出了问题。但通篇没查到这个错（soft lockup）是哪报的～

请前辈高人xdjm不吝赐教！卡了快一礼拜了　　　　　　

把这个驱动作为模块加载，报的错如下：
[root@ktdup5390 net]# insmod dm9000x.ko
dmfe_probe:start

因此初步判定是在 probe的这里出错了

dev->priv = db; /* link device and board info */
dmfe_dev = dev;

但不知道该怎么改
