I'm installing it now - I'll see if there is any difference wrt my
current difficulties, and report.  If the problems are still there, at
least I can comment out the dummy function and get you some feedback on
the virtex BSP.

Which problem are you referring to?  Probably not the Dummy Function
Problem, right?

I'm not convinced, as things were working until just very recently.  I
think the BSP is okay, is what I'm saying.  But since I have added an
interrupt handler in my application code, perhaps it is that?  But
again, it was working for quite some time before these exceptions
started showing up.
