DELQA (qe) breaking RLV12/RL02(rl) functionality

[Scott G Taylor <bub7734%yahoo.com@localhost>]

I'm finding that I can't have both an RLV12 (RL02) controller and a DELQA 
(non-turbo)
installed in my KA655 machine at the same time when running netbsd 5.1.

When both are installed, the DELQA runs fine.  However, access to the rl02 
drives
results in blocks of zero (NULL) data... if it doesn't crash the kernel.

Removing the DELQA board results is a perfectly working RL02 controller and
drives.  I actually went through three RLV12 (M8061) boards before accidentally
discovering that the boards weren't actually bad.  I just can't have both the
RL02 drives and the DELQA in at the same time.

I have moved boards around, as well as swapped in multiple boards of each
type with no success.

Before I spout the stripped kernel config, dmesg, etc., is there anything
that I don't know about this controller combination and NetBSD 5.1?
Is anyone running RL02/RLV12(M8061) and DELQA(M7516-YM) boards
together on their QBUS VAX with NetBSD, and actually using the RL02?
