Alex:
Thanks for your interest! Hope the following is of use to you. If you
would like, I can put the dump file (~60MB) in folder accessible via the
web.
Here's the page fault:

I'm a bit puzzled by the firmware_get failed line above. I suspect this
may be the problem, but I have not been able to resolve it. I've tried
disabling the bios on the FC cards, as well as messing with almost every
other conceivable option, but the same error appears. Thoughts?
