Ahh, nice expensive toy. :)

Hmm, a data overrun means that the device returned more data than we
expected. This is likely related somehow to the recent inquiry structure
size changes.
camcontrol doesn't yet do the short/long inquiry thing like the probe code
does.

Nope, that isn't working correctly, at least the standard inquiry portion
of it isn't.
I assume your camcontrol binary, libcam.a, and kernel were all built off
the same sources today?

Well, try this. Go into src/sbin/camcontrol/camcontrol.c, and in the
scsiinquiry() function, you'll see the following:
scsi_inquiry(&ccb->csio,
/* retries */ retry_count,
/* cbfcnp */ NULL,
/* tag_action */ MSG_SIMPLE_Q_TAG,
/* inq_buf */ (u_int8_t *)inq_buf,
/* inq_len */ sizeof(struct scsi_inquiry_data),
/* evpd */ 0,
/* page_code */ 0,
/* sense_len */ SSD_FULL_SIZE,
/* timeout */ timeout ? timeout : 5000);
Change the inq_len parameter from the full inquiry structure size to
SHORT_INQUIRY_LENGTH.
If that works, we can then try to figure out what is going on.
