MAKEDEV generates incorrect minor device numbers for {cua,tty}{i,l}R0.
Locking of control characters is broken in rp.c.
I suggest the following steps:
- apply the enclosed patches
- install the updated MAKEDEV
- recreate the RocketPort device files by running the newly
installed MAKEDEV
- compile a new kernel
- install the new kernel
- reboot the machine
- test
The standard RocketPort driver in FreeBSD has some additional problems:
- Only the first PCI RocketPort card works in a machine.
- open() might cause a kernel panic instead of returning ENXIO if
the device doesn't exist.
