Hi everyone,
I am running a modified version of kissattach on a
MMU-less uCdimm (Motorola MC68VZ328) to create an
AX.25 kiss network interface.
# kissattach -m 512 /dev/ttyS1 radio 192.168.0.9
# ttyS1 console mode off
Contents of axports file:
# name callsign speed paclen window description
#
radio KC0POH-1 9600 255 2 Radio
437.385 MHz
1200bps
The ifconfig of the interface is as follows:
ax0 Link encap:AMPR AX.25 HWaddr KC0POH-1
inet addr:192.168.0.9 Bcast:192.168.0.255
Mask:255.255.255.0
UP BROADCAST RUNNING MTU:512 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
frame:0
TX packets:0 errors:0 dropped:0 overruns:0
carrier:0
collisions:0 txqueuelen:10
However, when I try to ping a peer machine over the
radio link, I get a kernel panic.
# ping -c 1 192.168.0.8
PING 192.168.0.8 (192.168.0.8): 56 data bytes
Kernel panic: Aiee, killing interrupt handler
In interrupt handler - not syncing
Relevant kernel configuration is:
# Amateur Radio support
#
CONFIG_HAMRADIO=y
#
# Packet Radio protocols
#
CONFIG_AX25=y
# CONFIG_AX25_DAMA_SLAVE is not set
# CONFIG_NETROM is not set
# CONFIG_ROSE is not set
#
# AX.25 network device drivers
#
#
# AX.25 network device drivers
#
CONFIG_MKISS=y
We need to resolve this problem ASAP to complete the
radio link for our project. I strongly request experts
to help me solve it. Please let me know if you need
any other information.
Thanks in advance,
Sriram
