TI中文支持网我现在用的是DVRRDK3.5 和DM8168
在系统开机的过程中，kernel打印如下信息：

系统起来后，挂载的硬盘可以正常工作。
但是这些打印非常影响开机速度，它们大概需要二三十秒才能打完。
从打印信息看，它们并没有对硬盘驱动决定作用。想试图disbale检测，不知道怎么去关闭？
还请高人指点！
Louis：
你是直接SATA口接硬盘还是外界PMP在接的硬盘？另外，硬盘是SATA2的还是SATA3的？
Shujie Liu：
回复 Louis:
硬盘是stata2的。是外接PMP再接的硬盘。
非常期待您的解答！

回复 Shujie Liu:
请问楼上问题解决没？我也遇到这个问题了。
在ata1:STAT link down (sstatus 0 scontrl 300) 会等30秒，启动后硬盘挂载使用正常。
