If i leave it commented out, the module loads fine. That sounds like a typical bug during driver development... you're probably wedging the hardware by doing the wrong access. I didn't see the source for saa716x_read or write in the code you posted, so it's hard to say if there's a problem with them. Is your interrupt handler getting called? Is the device generating interrupts? > That part is then fine. Does MSI require any special tinkering ? Just pci_enable_msi() as usual. - R. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
