Thanks, that's exactly what I wanted to know. -28 is -ENOSPC which means that you've run out of available serial devices to register these others. If you wish to have three ports in an plat_serial8250_port array, you'll need to ensure that CONFIG_SERIAL_8250_NR_UARTS is set to at least 3. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - 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/
