Log Message:
Only downgrade modes due to an actual CRC error.  Downgrading on other errors
is anti-social -- especially given that there's no way to upgrade again short
of rebooting.

Also, downgrade UDMA modes more slowly.  It's entirely possible that they're
using an 80-wire cable, but it's just too long for the higher modes, or there
is minor crosstalk.
