I built linux- with the above, but the results are still the same and the EPC is not in

Are you searching the exact EPC value in
Usually you should find a function symbol which contains the EPC value in it.

Or you can do "mipsel-linux-objdump -d vmlinux" and search the EPC value.

The current error is:
Exception! EPC=80026290 CAUSE=00000020(Sys)
80026290 0000000c syscall

80026290 is not in, however, the objdump is much more informative and does contain that value. That particular syscall is in:

8002628c <kernel_execve>:
8002628c:       24020fab        li      v0,4011
80026290:       0000000c        syscall
80026294:       00401821        move    v1,v0
80026298:       14e00003        bnez    a3,800262a8 <kernel_execve+0x1c>
8002629c:       00000000        nop
800262a0:       03e00008        jr      ra
800262a4:       00601021        move    v0,v1
800262a8:       03e00008        jr      ra
800262ac:       00031023        negu    v0,v1

Does that provide any clues?
I have to go now. I will take another look when I return, but I have looked at kernel_execve before.
