Hello,

Successfully using KPC9612 and kernel 2.4.18 but *WITHOUT* fpac which hanged
the system. Otherwise, 2.4.18 runs well with lot of annoying messages into
syslog and message of that kind:
Dec 21 17:12:45 f6fgz kernel: NET: 5 messages suppressed
The cause is due to listen. Don't use it and you will be happy.
My config:
CONFIG_HAMRADIO=y
CONFIG_AX25=m
CONFIG_NETROM=m
CONFIG_ROSE=m (not used)
CONFIG_MKISS=m

My script:
/usr/sbin/mkiss -s 19200 -l /dev/ttyS1 /dev/ptyp1 /dev/ptyp2
/usr/sbin/mkiss -s 19200 -l /dev/ttyS0 /dev/ptyp3 /dev/ptyp4
/usr/sbin/kissattach -m 256 /dev/ttyp1 vhf  f6fgz
/usr/sbin/kissattach -m 256 /dev/ttyp2 uhf1 f6fgz
/usr/sbin/kissattach -m 256 /dev/ttyp3 uhf2 f6fgz
/usr/sbin/kissattach -m 256 /dev/ttyp4 uhf3 f6fgz

/etc/ax25/axports:
vhf F6FGZ-4 19200 255 2
uhf1 F6FGZ-3 19200 255 7
uhf2 F6FGZ-5 19200 255 4
uhf3 F6FGZ-6 19200 255 7

And I use Xnet v1.36 along with a local WLAN.
