Are you sure you've given parport_pc the correct IRQ/DMA? It doesn't seem to be able to detect them very well over here, so I need a line such as: options parport_pc io=0x378 irq=7 dma=3 but YMMV :) > > Davy -- Zinx Verituse (See headers for gpg key info) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
