That sounds very strange, and that kind of combo was not unusual in the
past (although not with NetBSD I would guess).
A few things comes to mind:
I assume that the bus chain was kept intact as you added/removed cards
and fooled around. You know that depending on which backplane you have,
the bus might not run in a straight line.
Also, make sure that you don't have any conflicts for interrupt vectors.
The RLV12 sets the interrupt vector with jumpers. I can't remember for
sure how the DELQA do, but I seem to remember it being fixed by a jumper
or two on that one as well.
I don't know how good the RL device driver is, but there might be
problems in there as well. I doubt it has been tested or exercised much...
But if it works when the DELQA is removed, that would suggest the driver
should be ok.
Feel free to post the dmesg. Maybe something will stand out.
My main suspect might be the interrupt vector, but I would have expected
some error or warning message if we have a conflict...

Interesting. I seem to recall having problems reading RL02 packs on
NetBSD just giving me NULL bytes as well. I may have had the same
combination (netbooted off a DELQA/DEQNA), running off NetBSD 1.5. It
worked fine under VMS, so I just suspected that RL02s didn't really work
with NetBSD anymore.
