One of these caused an interrupt, and for some reason none of the drivers
recognized this as it's own interrupt.

I suppose it's the nell interrupt handler that sometimes screws things up.
I'm staring at the code, but I don't see the culprit. Since it happens for
you even w/o any pcmcia card, only a trivial part of the code is involved.

Not that I'm aware of.
