That could easily be due to another problem I'm currently working on.  At
least, it sounds familiar -- and it's related to interrupts in general.

Maybe, but it suffers from the problem I just mentioned, particularly on
slower devices (but not exclusively).  Indeed, that's why I'm working on
it.  I don't have a SPOT (or GENERICSBC) kernel available at the moment,
but I'll see if I can put something together after I'm done with the
present project.
