I'm having difficulty with a system that has two 16 port PCI
RocketPort multi-port serial cards. The first card (rp0) works just
fine. The second card (rp1) can send data, but can't recieve.

Using kermit to connect to one of the /dev/cuaR16 .. /dev/cuaR15
ports, I can actually login to a remote system, and do commands, but I
get *nothing* back. The nice little red light on the external expander
for the part I'm using flashes, even for recieve traffic.

And yes, when I move a cable from rp1 to rp0, it works just fine.  :)
One step further, I've had the rp1 card in another system (where it
was rp0, the only RocketPort card) and it worked just fine. 

I'm running 4.3-STABLE. Here are the rp parts of dmesg:

rp0: <rp> port 0xec00-0xec7f irq 9 at device 18.0 on pci0
RocketPort0 = 16 ports
rp0: driver is using old-style compatibility shims
rp1: <rp> port 0xe080-0xe0ff irq 15 at device 20.0 on pci0
RocketPort1 = 16 ports
WARNING: "rp" is usurping "rp"'s cdevsw[]
rp1: driver is using old-style compatibility shims
WARNING: driver rp should register devices with make_dev() (dev_t = "#rp/0x10088")

In looking at the code, it seems that the usurping warning is because
both rp0 and rp1 use the same major device number.

The devices in /dev seem reasonable:
