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.

Thanks.
