GVP IO-Extender

[Ken T. <ke...@we...>]

I have a GVP IO-Extender parport driver working but with a problem. It
hangs linux if the printer is turned off and on after the module has been
unloaded.  The cause is an interrupt without a handler, once interrupts
from the chip are enabled they can't be disabled, well they can but then
continuous interrupts are generated. There are comments in the 2.2.n code
that say the same thing.

What's the way to handle this situation ?
