I reload the drivers quite often during testing, and have no such
problem -- except if there has been an Oops...
Otherwise: How can I reproduce this?

There is a problem somewhere, and I guess it only happens with SMP,
because I cannot reproduce it. The best way to solve it would be if
someone with time and knowledge would do a code review of the
irq handling code in av7110.c.
