    This warning is not the first produced by your system, see the W flag in
    the line above. Can you find an earlier warning in your dmesg/log? Or is
    it similar to this one?

    Hi there,

    yes you are correct, I found another one earlier, initially I thought is
    the same but it is not.

    Hmm... This shouldn't happen. Can you please attach full kernel log
    including the boot messages?

    Does the problem occur w/o ath5k? I don't really see how ata_piix can
    trigger the WARN_ON().
