CPU'

Kernel: Linux 2.6.15
Target: mips (32bit, big endian), SMP 4way (2way also crashes)
preemption model = server (least preempt), do not preempt the big kernel
crash
Board: Broadcom 1480B

How to reproduce: I made a bash script which awks a file line by line...
        while true; do
                echo "crash me..."
                ls
        done

The neither the 'echo' or 'ls' commands are necessary. Originally I
would see it crash in a bash script which calls awk, or during the init
sciprts sometimes. The above script causes it to crash within a minute
every time I have run it.
