attempt to access beyond end
添加ramdisk(ramfs2048.img)，在向/ramdisk下拷贝大于1M的文件时出现如下错误信息：...
attempt to access beyond end of device
01:01: rw=1, want=1025, limit=1024
attempt to access beyond end of device
01:01: rw=1, want=1026, limit=1024
attempt to access beyond end of device
...
从网上搜了一下,在http://mailman.uclinux.org/pipermail/uclinux-dev/2004-October/029045.html发现一封邮件和我的问题有些相似，内容如下

Looks like you RD is limited to 1Mb
> I have config the ramdisk to 2048KB in Misc. configuration-> (2048K) RAMFS

Only if you kernel has set the RD size lower than the default of 4096,check your kernel config for the ram disk size,that may be your problems,
但是怎样设置RD啊？
试图在kernel/Block devices/RAM disk support/Default RAM disk size中修改default ram disk size(默认值是1024)，但是这一项修改不了.
怎么办呢？
