Wasn't the problem with outbound flush just that that functionality didn't 
actually get implemented?

It sounds like the 21285 is trying to perform some transaction on the bus 
either to satisfy a read or to unload its write FIFO (and it's stalled the 
SA110 while it does so) but it keeps getting a retry response.  Can you 
examine the PCI bus and see what's going on in terms of the address that the 
Footbridge asserts and the response it gets from the target?

I've never seen this on any of the machines I've worked on, but none of those 
have used the same southbridge that you've got.
