Strange.

So NMI and sysrq doesnt help. I suggest you a few things:
Try to make the bug easy to reproduce. Force the Oracle dumps again and again to crash the box. Can you try it or its a production machine?
BTW, can you describe this "Oracle dumps" in more detail? What do they do? Save lots of data to disk and thats all or ?
