Significant boot error message ?

[Bob Goodwin]

        When I boot FC6 I get a few error messages:

        Red Hat nash version 5.1.19 starting
        usb 1-2 device not accepting address 2, error -71
        ata2; port failed to respond (30 secs)
        ata2: SRST failed (status 0xFF)
        ata2: SRST failed (err_mask=0x100)
        ata2: SRST failed (status 0xFF)
        ata2: SRST failed (err_mask=0x100)
        ata2: SRST failed (status 0xFF)
        ata2: SRST failed (err_mask=0x100)
        ata2: reset failed, giving up

            Reading all physical volumes. _etc. things proceed normally
        after this._

        Other than that everything seems to be working.  The only usb
        device connected to the computer is a cheap looking Dell mouse
        that came with it.  FC6 Linux is installed on a second sata
        drive since the computer came with Windows XP which I elected to
        keep intact.

        Other than the time it spends doing whatever this indicates,
        slowing the boot process, I don't see a problem.  But I would
        like to "fix" it if anyone has any idea what it means.

        Thank you.
