Rod,

We, too, have used the BDI2000 in such a fashion.  I agree that it can 
be invaluable when debugging the interaction between a userland 
application and a kernel driver.

Can you describe the method you use to do this?  Our process is a bit 
cumbersome, involving putting a breakpoint in a driver's ioctl() 
function that will only be called by our application.  Once it is hit, 
we use add-symbol-file to get the information for our application's 
binary, and we are able to proceed.  This is on a PowerPC chip, with the 
special "BDI2000 support" hack turned-on.

Is your method any "cleaner"?

Thanks,

John
