>Description:
The conflict detection code does not allow for the possibility that
a device does not have an IO address.
>How-To-Repeat:
I'm specifying the config lines like this, with no io address:
# Specialix XIO 8-32 port terminal host card
device si0 at isa? tty irq 12 iomem 0xe0000 vector siintr
device si1 at isa? tty irq 14 iomem 0xe8000 vector siintr
#device si2 at isa? tty irq 15 iomem ? vector siintr
#device si3 at isa? tty irq ? iomem ? vector siintr
