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?
