After using cdrecord for over a year without incident, I have recently
begun to see SCSI command timeouts during the fixating portion of
writing a CD9660 data disk.  The disk is still mountable upon completion,
but only on a CD-RW drive.  The output from cdrecord is below.
These errors occur with both CD-R and CD-RW disks from different
manufacturers.  The hardware configuration has not been changed at all,
and I have checked the SCSI cabling many times.  The CD-RW drive has been
flashed to the latest firmware release.  I don't know whether this
is at all relevant, but the problem seemed to begin shortly after the
changes to libcam in May-99, after remaking world and updating the
cdrecord port.

I have also seen similar command timeouts while trying to blank
a CD-RW disk with the "blank=fast" option.

I would be interested if anyone else is experiencing similar problems.
