I've been wondering about this, and it is questionable whether we should allow any serial port which isn't owned by the legacy platform device (the one called "serial8250", iow by the 8250 driver itself) to have the base addresses and interrupts changed. IOW, we apply this "fixed port" to any port registered by probe modules external to the 8250 driver itself, such as PCI, PNP, etc. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
