    SubjectRe: SATA link detect failed, works fine

    Hi, it's timing related.

    I just tried booting with an initrd, and i want to capture the full error
    message, but with initrd, the problem went away.

    The only difference between the two config is:

    --- .config.old 2009-12-24 09:16:31.000000000 +0800
    +++ .config 2009-12-23 19:05:17.000000000 +0800

    Right now, I can reproduce this problem only when I
    running with a specific kernel config.

    If I attach a serial console or use initrd to capture
    the fail boot log, the problem disapeared. Even running with the exactly same config, no problem.

    So I will say that it's very hard to reproduce this, it's very
    subtly timing related.

    I remember when running 2.6.32-rc8 and 2.6.32, the same
    problem happened twice, I just can't reproduce it.
    And with 2.6.31.x, never running into this.

    Oh well.
