Public bug reported: In 14.04, there is a bug in /usr/lib/pm-utils/power.d/wireless script at line 23. It should "enabled" at the end of path /sys/class/net/$1/device/enable.
I always get an ENOENT error in /var/log/pm-powersave.log when that hook runs, inspite of active wlan0. Running hook /usr/lib/pm-utils/power.d/wireless false: cat: /sys/class/net/wlan0/device/enable: No such file or directory /usr/lib/pm-utils/power.d/wireless false: success.
