For studying Linux kernel, I want to let one run debugging Linux as client, the other as host. The two laptops don't have serial port, just have LAN and usb ports. How can I configure them to get early kernel print message? I ever asked a lot of people, but don't get answers. Please give me some practical advices, thanks in advance. stanley -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
