This time is a significant part of the total boot time. This patch series introduces a module parameter that can be used to tell the kernel which ports to skip, and the second patch adds a DMI list for known setups so that for known cases users don't have to add any parameters at all. -- 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/
