linux2.6内核版本配置支持ipv6，通过make menuconfig查找ipv6相关选项，设置成Y后，保存，比较.config文件与.config.old文件区别找出来，手动修改openwrt.config文件添加ipv6相关选项，编译可以通过，但是uboot重启后报错。
手动修改openwrt.config添加的内容如下：
CONFIG_PACKAGE_kmod-iptunnel4=y
CONFIG_PACKAGE_kmod-iptunnel6=y
CONFIG_PACKAGE_kmod-ipv6=y
CONFIG_BUSYBOX_CONFIG_FEATURE_IPV6=y
CONFIG_BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IPV6=y
CONFIG_PACKAGE_kmod-ip6tables=y
CONFIG_PACKAGE_kmod-sit=y
进入uboot下升级后，reset报错内容如下：
错误1

此时怀疑是内存分配太小的原因，setenv修改bootsys=bootcheck 0 $(mtdparts) mem=2048m 大小由1024m变成2048m保存再次重启，报错如下

请教各位这是出了什么问题? 该如何解决？是不是手动添加openwt.config文件的时候少添加了什么东西还是？有没有大神配置成功过？求经验，谢谢！
