Does the machine still boot 5.3, or does the line:

mean that the drive/controller is actually mussed up?
If you can boot 5.3, it would be very helpful to see a dmesg
from that. If not, it might still be somewhat enlightening to
see where the 6.2 bootup stops, if you can capture that.
If the SCSI drive or controller really has gone south in
some fun, horrible way, you might try physically removing
them, as a malfunctioning controller can cause a rather
long* pause in the disk-probing sequence.
If you have already removed the SCSI stuff and the 6.2
disk still hangs after the SATA probe and you can't find
any way to capture the output, you might try posting the
make and model, as there are some dreadful pieces of
garbage out there that FreeBSD has some difficulty with.
* Potentially limited only by how long your machine continues
to have power connected.
NB: In my experience OpenBSD is much better at
playing fast&loose with garbage hardware than
FreeBSD. Whether this is a good thing I would not
hazard to guess.
