General hint, if you get problems on an Amiga with a bridgeboard:
If the problems are really weird, everytime different, THEN pull out
the bridgeboard, press EVERY chip tight into it's socket, check that
all chip pins are aligned with the socket contacts, and finally put
the bridgeboard back into the Amiga tightly. There seem to exist some
sockets of mediocre quality. On my machine, this procedure has to be
done every half year...

Now the different point in your story is that you had the same with
a second bridgeboard. Perhaps one of your other cards is not
autoconfiguring and collides with the address space of the bridgeboard?
(Bad, bad practice of some hardware designers, but really existing.)
