    SubjectRe: 2.6.32.2 SATA link detect failed, 2.6.32.1 works fine

    Hi,

    with this patch, the problem still exists.

    ata1.01: XXX debounce start, SStatus=4
    ata1.01: XXX debounce done, SStatus=4, DET stable for 520 msecs
    ata1.00: SATA link down (SStatus 0 SControl 301)
    ata1.01: SATA link down (SStatus 0 Scontrol 300)
    ...
    VFS; cannot open root device ...

    The kernel just panic, and I can't see what's the messege printing before
    that.

    So, I tried 'console=ttyS0 console=tty1',full dmesg attached。

    $ hdparm -I /dev/sda:
