请教SBC2440的双网卡问题

我用的是SBC2440板，为什么光盘里带的已编译内核都只是支持单一网卡？
我买这板是因为我需要同时支持双网卡，请问该如何配置内核？
或者能不能给个配置？

还有，我把光盘里自带的vivi烧进去后，发现和板子买回来时的vivi不同，原来提示符是Supervivi，现在变成了FriendlyARM，而且没有了菜单功能，可不可以提供一个板子原来带的vivi？

我手上只有for QQ2440的kernel，不太清楚SBC2440内核的配置。不过既然SBC2440是双网卡的硬件，我相信光盘上自带kernel默认配置里应该有这两个网卡的配置。
如果你用的是menuconfig, 网卡设备的配置一般在Device Drivers->Network device support下面

我把默认配置了DM9000网卡驱动的配置文件导入后，再把CS8900网卡的驱动模块配置进内核一起编译，最后竟然是8900可以用，而DM9000不能用。

在超级终端下用 ifconfig eth1 up  启用DM9000网卡时，出现如下一行提示：
enabled_irq(51)  unbalanced from c0173b7c
不知是什么意思


请问友善在哪里有提供SBC2440的技术支持？有没QQ群或BBS？

.......

irq(51)是DM9000用的IRQ （EINT7）号，这个出错信息的意思是驱动对IRQ的enable和disable次数不匹配

请问该如何解决呢？

是不是内核配置错误的问题？

一般来讲，这是驱动程序的问题，至于具体如何解决，你得看kernel里面dm9000的驱动程序源代码，以及SBC2440上对dm9000的硬件初始化配置部分源代码

但是单独把DM9000驱动模块编译进内核却可以正常使用，只在两者同时编译进去才会出问题。

我是做软件开发的，不是做硬件驱动开发的，所以对驱动源码根本不懂，要自己看的话就头大了。

而且友善主页上提供的就只有单网卡的配置，不知是不是不支持双网卡的同时使用。

把
1. 单独编译dm9000时kernel启动的log
2. 同时编译dm9000和CS8900时kernel的启动log
3. 同时编译dm9000和CS8900时执行"ifconfig eth1 up"的kernel信息
都贴出来看看吧

<4>enable_irq(51) unbalanced from c0173b7c

从这两个log看，问题应该不是由"enabled_irq(51)  unbalanced from c0173b7c"引起的。这个错在单独编译DM9000时也有。我想这是因为友善之臂移植DM9000驱动程序时多写了一个enable_irq()引起的，内核只是检测到次数不匹配报一个warning而已。
另外，从同时编译DM9000和CS8900的内核启动log看，这两个驱动似乎都成功加载了，没有明细的出错信息。看不出DM9000为什么会无法使用。
我建议你把CS8900作为Kernel module不要编译进内核，在这种情况下先确认DM9000可以正常使用，然后再从文件系统加载CS8900的module
