I recently had report about alike problem with "PIONEER DVD-RW DVR-215
1.19" drive. Don't you have the same device or another Pioneer?

In that case this patch:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/cam/ata/ata_xpt.c.diff?r1=1.3.2.29;r2=1.3.2.30;f=h
allowed system to boot, though problem seemed to be hardware. Try this
patch, it at least may give additional info about the problem.
