Have you got a chance to test this, I have gotten some similar problem
and got rid of them with the following patch applied (credit goes to
gibbs@ who fixed this last November):

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/cam/cam_xpt.c.diff?r1=3D1.142=
&r2=3D1.142.2.2

This might be important since I think this has affected many users who
wants to use multiple LUN's, and thus warrants a new errata candidate
for 5.3-RELEASE.

Thanks in advance!
