drivers/misc/parport_pc.c
static int irq_probe_ECP(struct parport *pb)
static int irq_probe_EPP(struct parport *pb)
static int irq_probe_SPP(struct parport *pb)

Although only the ECP one actually does anything without ADVANCED_DETECT
set.

It's supposedly in the generic parport code.

I don't think it's a PLIP problem per se, it seems like the parport code.

I'll set mine to what yours is and see what I get.
