"Bad trap at PC: 3000xxxx, SR: xxxx, vector=xxx Not tainted"

[chao yu]

I port the linux 2.4 kernel to our mpc8541 board, but when it executes the
run_init_process("/sbin/init") in the init function, it will disaplay "Bad
trap at PC: 3000xxxx, SR: xxxx, vector=xxx    Not tainted" continually. The
ramdisk is from ELDK 4.0 package for 85xx which is pre-built. Who can tell
me what was happened?
