I built linux-2.6.23.9 with the above, but the results are still the

Are you searching the exact EPC value in System.map?
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 System.map, 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.
Thanks
