This is a FreeBSD problem, but it's not a hal problem per se.  I think
the GEOM/SCSI people are working to hide these kind of messages, but in
the meantime, you either need to live with them, stop using hal, or tell
hal to stop probing that device.

The way hal works is that it periodically probes devices to determine if
there is media changes.  In this manner, hal can auto-mount volumes.  If
you do not want to auto-mount media from this device, then search the
archives for ways to manipulate the .fdi files to stop hal from probing
this device.  Again, the ideal solution would be for the kernel people
to hide these messages behind verbose booting.
