OK, now this is impossible (11/23+ and RL02-RLV12 problem)

I have this 11/23+ system with an RL02 drive and the RLV12 controller that
won't boot XXDP. Attempting to boot XXDP v2.5 either halts at 000154
during the initial boot, or gives ?RD ERR messages from XXDP. The behavior
is a little random - sometimes it halts at 154, sometimes you'll get a few
?RD ERRs and then it'll lock up, and sometimes you'll get far enough to get
an actual prompt from the XXDP monitor, but even then you can't run
anything. You just get more RD ERRs.
OK, I know - bad drive or bad pack, right? Well, I've tried two different
RL02 drives and two different XXDP packs with the same results. Better yet,
I've connected one of those RL02 drives to another -11 (this time a 11/04
w/RL11) and that same drive with those same packs boots and runs with no
complaints. The drive even passes all the ZRL??? diagnostics and ZRLM??
can scan the entire pack and finds no bad sectors.
Better yet, I have another RL02 pack with RSX-11M v3.5 and that boots and
runs on the 11/23 with the same RL02 and RLV12 with no apparent problems.
Now that's really impossible - the same drive that won't boot XXDP will boot
How can this be? It almost seems like it has to be a software problem
with XXDP, but XXDP obviously works on a 11/23 and the RLV12/RL02. Is there
some strange hardware compatibility or ECO issue with the RLV12 or the
11/23+? Is there something XXDP does with the drive that RSX doesn't?
I'd run diagnostics on the RL subsystem, but I don't really have any other
load path for XXDP on this system. I did pare the system down until there
are only three cards in the backplane - CPU, memory and RLV12. No joy. And
just on a whim I tried a different cable for the RL02 - still no joy.
