The 713 is a 753 lookalike for ESDI disks.  If we put two controllers in
the same chassis at the same (default) interrupt level 2, the second
controllers occasionally gets:

Jan  3 10:28:38 peach vmunix: xdc1: controller not responding
Jan  3 10:28:39 peach vmunix: xdc1: system lost interrupt from controller. SOFTWARE RECOVERED

When things are busy.  When we reverse the order of the controllers we
get:

Jan  3 14:26:10 peach vmunix: xdc0: controller not responding
Jan  3 14:26:13 peach vmunix: xdc0: system lost interrupt from controller. SOFTWARE RECOVERED

When we set the latter controller to priority 3 (at the suggestion of
Xylogics), we get:

Jan  2 18:32:04 peach vmunix: xd4g: read fixed (soft ecc corrected) -- blk #212800, abs blk #212800
Jan  2 18:32:04 peach last message repeated 6 times
Jan  2 18:32:04 peach vmunix: panic: dup biodone

That is, first some ecc errors on a brand new disk that don't appear when
the priorities are the same.  Then a biodone panic (whatever that is!).

Here is our bootup config:
