IceCube 400 is OK too, so all the three disks of mine that claim to be
TYPE_RBC work (...WRT the new command and response conversion code
path).

No difference with sbp2's former MODE_SENSE conversion put back into
sbp2_check_sbp2_response().

As to be expected, no difference without that workaround.

I will try to get nearer the point of failure during the week.
