Please submit the patch to Alan Cox along with an explanation
of the problem.  Or send it to me and I'll forward it to him.

(If you disable the "current" config you don't need to reboot.)

If you were trying to use the mwave module with IRQ 4 then

You shouldn't ever have to use MWAVE_FUTZ_WITH_OTHER_DEVICES.
Nevertheless, we should fix this bug.  Can you send me a
patch?
