* suggest 1: Fix it in the kernel side in "enable" or "enabled".
/sys/class/net/wlan0/device/enable
or
/sys/class/net/wlan0/device/enabled <- being ideal
* suggest 2: Revert by lp #1299975
[ "$(cat /sys/class/net/$1/device/enabled)" = "1" ] || return 1
to
[ "$(cat /sys/class/net/$1/device/enable)" = "1" ] || return 1
* suggest 3: In the same way as a lp #1299975, modify pm-utils package
again.
