An extra note on this... most of the faults worth responding to here are
serious enough that the interface should just be shut down, or at least,
the device will need to be init'd again.
I'm surprised no handling was implemented in the first place - makes it
very difficult to debug problems when you're prototyping new kit. The
driver is written as though these interrupts are meaningless!
