Re: kern/58459: iwm0: fatal error on shutdown and reboot + other wifi woes

["Marc Coquand" <marc@mccd.space>]

Hey,

So I think that the iwm0: fatal error on shutdown is a red herring, and
that my wifi issue (that wifi stops working, even with reboot) actually
stems from hibrenation. I have the following lid_switch for powerd.

case "${2}" in
pressed)
        # Wait for 1 second
        sleep 1
        # Suspend
        # As in sleep_button, kill some daemons.
        #
        logger -p info "${0}: Sleeping, powering off network daemons"
        /sbin/sysctl -w hw.acpi.sleep.state=3
        exit 0
        ;;

released)
        logger -p info "${0}: Waking up, restarting network daemons"
        exit 0
        ;;

*)
        logger -p warning "${0}: unsupported event ${2} on device ${1}" >&1
        exit 1
esac


Now my thinking is that I could instead change this to also
deactivate the network daemons as well, so I tried this solution.

case "${2}" in
pressed)
        # Wait for 1 second
        sleep 1
        # Suspend
        # As in sleep_button, kill some daemons.
        #
        logger -p info "${0}: Sleeping, powering off network daemons"
        /etc/rc.d/dhcpcd stop
        /etc/rc.d/wpa_supplicant stop
        /etc/rc.d/network stop
        /sbin/sysctl -w hw.acpi.sleep.state=3
        exit 0
        ;;

released)
        logger -p info "${0}: Waking up, restarting network daemons"
        /etc/rc.d/network start
        /etc/rc.d/wpa_supplicant start
        /etc/rc.d/dhcpcd start
        exit 0
        ;;

*)
        logger -p warning "${0}: unsupported event ${2} on device ${1}" >&1
        exit 1
esac


Now, I have not experienced wifi issues. However, it seems the daemon
does not automatically restart. `cat /var/log/messages | grep "Waking
up"` does not yield any messages, so its as if it never runs the
`released)` part of the code.

Anyone knows what I could be missing?
