启动新内核出现错误：Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004

查阅内核源码，才知道exitcode=0x00000004  代表的是 SIGILL （非法指令）

出现这个错误的原因是交叉编译器用的是EABI借口，所以内核也要用EABI接口才行：

book@book-desktop:/work/nfs_root$ arm-linux-gcc -v

Using built-in specs.

Thread model: posix

gcc version 4.3.2 (Sourcery G++ Lite 2008q3-72) 

Embedded application binary interface （EABI）, 即嵌入式应用二进制接口

 

解决办法:重新配置内核支持EABI

 

make menuconfig

Kernel Features  --->

　　   [*] Use the ARM EABI to compile the kernel

　　   [*]   Allow old ABI binaries to run with this kernel (EXPERIMENTAL)
