Hm .. from the -v output it looks like the first ATA channel is not
resetting properly for the probe. We'll need to get a better idea of when
the problem appears since a lot has changed between January and now.

Some more stuff to try:

1. Boot up the new kernel off a cold power cycle, in case freebsd is
leaving the controller is some inconsistent state.

2. Download the February 2005 -STABLE snapshot and try booting that.
That can be the first step in a binary search for the offending commit.
