Package: ipw3945d
Version: 1.7.22-2
On bootup the daemon is started by modprobe when the ipw3945 module is
loaded. A few seconds later the daemon is started again from
/etc/init.d/ipw3945d. The strange thing is the daemon is in fact
started twice. As there are 2 daemons fighting for the same card, the
network is not functioning.

I tried adding
if test -e "${DAEMON_PID_FILE}"; then...
to the start_daemon() section of /etc/init.d/ipw3945d, but this did not
work as the pid file was not yet written when the daemon was started the
second time. The start-stop-daemon process is probably still running at
that time, but not yet ipw3945d.
It works with a pgrep though (also matches the start-stop-daemon process
i guess). So this does the trick:
start_daemon() {
if have_sys_entries; then
remove_stale_pid
if pgrep ipw3945d; then
log_warning_msg "ipw3945d already starting!!"
else
log_daemon_msg "Starting ipw3945 regulatory daemon" "ipw3945d"
start-stop-daemon --start --quiet --chuid "${DAEMON_OWNER}"
\
--exec "${DAEMON_BINARY}" --pidfile
"${DAEMON_PID_FILE}" \
--oknodo -- --pid-file=${DAEMON_PID_FILE}
--quiet \
--log-file=${DAEMON_LOG_FILE} > /dev/null 2>&1
code=$?
log_end_msg ${code}
sleep 1
fi
else
log_warning_msg "Not starting ipw3945 regulatory daemon, driver not
loaded."
fi
}
