Freeing init memory

请教一个问题：
TQ2440
内核：2.6.25.8
.config:config_Embedsky_W35
使用NFS文件系统。
问题是这样的，我使用config_Embedsky_W35自己做zImage载入开发板，启动后一直卡在“Freeing init memory: 176K”，直接载入提供好的内核载入，就能够进入console，说明根文件系统没问题，但是我自己做的内核，使用的提供的配置文件config_Embedsky_W35，也没乱改什么，卡住的原因是什么的？

下面是串口的打印信息：

文件系统/etc/init.d/reS中的net_set屏蔽掉了没

是rcS中吗？net_set是什？我看移植手册里没讲这个呀

我这个并没有net_set行，我以前一直都是使用的开发板上给的内核，NFS文件系统做的练习，一直都没事，就现在开始自己编译内核了，才出现的这个问题

你在你的文件系统内部搜索下，可能位置不同。

谢谢“wbz073”的帮助。但是问题不是那里。
问题原因是编译器的版本问题，我自己的内核使用的是3.4.5的版本，而文件系统中的busybox使用的是4.3.3.
因为以前直接拿的天嵌的内核用，阴差阳错，人家编译好的内核就是使用的4.3.3的版本，自然是能读取文件系统的。
而我自己编译了内核，出现了内核是3.4.5的编译器，文件系统4.3.3的编译器，这种情况。所以没法执行Linuxrc，也没法加载rcS文件。
解决方法：重新make install一下busybox，将新的bin/ sbin/ usr/ linuxrc文件放到文件系统即可。
