Doubtful.  The generic probe code will issue inquiry, test unit ready,
mode sense, and the VPD serial page inquiry command.  All devices,
regardless of type, should be able to handle these command.  "Handling"
also means properly responding to commands that are not supported.

FreeBSD has probed processor target devices ever since it grew a SCSI
layer.

Perhaps you should try updating the firmware on your backplane.
