The parport driver isn't even used, since ftape's fdc_parport.h only
uses parport if CONFIG_PNP_PARPORT is set. This is fixed in
ftape-4.03.
But there is another bug in the auto irq detection for the non-parport
case. It is in trakker.c line 1121 (ftape-4.03.tar.bz2):
trakker->IRQ = irq;
This only sets the IRQ in the trakker structure, there should be
another line after this:
trakker->IRQ = irq;
fdc->irq = irq;
Claus, can you fix this? This is what led to the strange line in
Tony's report:
> [010] trakker.c (trakker_interrupt) - BUG: Wrong IRQ number (7/-1).
