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
