急！！～～大家帮我看看啊，错了很久了

i.MX21的板子，不能NFS，我修改了cs89x0.c里的驱动，因为这个版本内核（2.6.32）里网卡驱动没有MX21
具体改的地方是加上了netcart_portlist和irq_map，但是启动时一直说“Failed to open eth0”


cs89x0:cs89x0_probe(0x0)
cs89x0.c: v2.4.3-pre1 Russell Nelson , Andrew Morton
eth0: cs8900 rev K found at 0xe0000000

Please append a correct "root=" boot option; here are the available partitions:

1f01            1920 mtdblock1 (driver?)
1f02           30720 mtdblock2 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,255)

不懂，帮顶下

谢谢各位，问题解决了，原因是cs89x0.c里中断号问题，还有就是内核选项里CS89x0_NONISA_IRQ这个没选择上。
