Subject: MPC8272 runs application with segmentation fault

Dear experts,

I have two hardware boards, one uses MPC8245 and the other one uses MPC8272.
Initially, I use the MPC8245 board to port Linux 2.4.20 and write some applications.
I already do a lot of test on the MPC8245 board and all my application programs work
fine.

After this, I use the same kernel configuration and same file system that are being used
by the MPC8245 board to port the whole system to my MPC8272.
Now, I can boot the kernel and run busybox well. However, when
I run my application programs, I always get segmentation fault. Following is a strace
dump. Could anybody give me some idea?

Thank you
Dennis
