It's generally better to send SCSI problems to the SCSI list
(freebsd-scsi@FreeBSD.ORG). You're much more likely to get a response.
The more noise that hits this list, the less I read it. :)

In general, I would say you have a cabling or termination problem. But,
there is another possible explanation.
Your enclosure seems to be the device that may be generating the problems,
and the parity errors only seem to happen during probe of non-zero luns on
that device.
Try the attached patch for sys/cam/cam_xpt.c. It will hopefully disable
multi-LUN probing for that device. I think I've properly separated the
vendor ID from the device id, but it could be that you'll need to tweak
this a bit.
Note that the patch is against -current, but it should apply to -stable all
right.
