I was able to disable everything else that had external hardware access
to flash and the IXP's memory and the problem still appeared. I have now
been able to determine that the fault lies with some memory scribbling
done by one of our own kernel modules.
There is no need to further bother this mailing list with this issue.
Thanks David and Brian for your input in this problem :)
