No, you're quite right.  In fact, it's very useful for me to know that 
the code crashes even when you don't have a resized firmware area. 
Don't even bother trying it with a resized firmware tomorrow :)

So is it correct to say that you've just switched from the diskonchip 
driver which is distributed as part of, to the diskonchip 
driver from the MTD CVS repository?

If so, then any of the changes between the MTD version in and 
the current CVS are potentially the problem, not just my latest change 
to diskonchip.c

The version of diskonchip.c in is 1.45.  I don't see anything 
in the changes between then and now (1.50) that should cause the 
behavior you're seeing, which means either the problem is in a different 
file or I'm just not seeing it :)

I'll stare at it some more tomorrow.  Anyone else (Thomas?) have any 
ideas where to look?

On the contrary, you're much better at providing the right information 
than most people.
