I think that this must be it. I had the blindingly obvious idea of looking
at the chips interrupt mask in the watchdog (which is getting called). The
chip has posted a TX complete interrupt. The kernel hasn't done anything
with it so I assume it isn't routed.

Until I get back from travelling and can install 5.1R, this at least gives me a 
hook to continue driver development - fairly icky though using the
watchdog to trigger the interrupt handler!
