I remember this one. Sort of. It has to do somthing with a unused pin /
interrupt on the X1. This can trigger an interrupt (storm) that
completely chokes the kernel. Solution is to not install this interrupt
handler. There was some discussion on this list how to do it proper. But
I don't know the outcome.
