 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=3D3
         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=3D3
         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?
