Significant boot error message ?

       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.
