[cristian <972604@xxxxxxxxxxxxxxxxxx>]

I've tried 4.2.0-18.22 kernel by installing linux-
image-4.2.0-18-generic_4.2.0-18.22_i386.deb and linux-image-
extra-4.2.0-18-generic_4.2.0-18.22_i386.deb (available at
https://launchpad.net/~ubuntu-
security/+archive/ubuntu/ppa/+build/8272202 ). Using this kernel,
regression is disappeared (same as 4.0.0-1 test kernel): there are both
hp-wifi and phy0 interfaces in rfkill list output, there are no
(back)traces in dmesg | tail output and if I press the wifi switch
button, network manager applet shows wifi status properly. Anyway,
original bug (as described at the top of this report) exists yet: if I
execute the workaround, colors are reversed.

I'll install Ubuntu 15.10 too in order to confirm (or not) if the
regression is definitively fixed and I'll update the bug report.

Title:
  168c:001c [HP Compaq Presario C700 Notebook PC] Wireless led button
  doesn't switch colors

Status in linux package in Ubuntu:
  In Progress

Bug description:
  I'm using Lubuntu 11.10 Oneiric Ocelot. My wifi chip is supported from
  ath5k drivers. The led button blinks between red and blue light and
  its pressure does anything.

  WORKAROUND: I tried to type:
  echo none > "/sys/class/leds/ath5k-phy0::tx/trigger"
  echo phy0radio > "/sys/class/leds/ath5k-phy0::rx/trigger"

  and in this way I can control the color of the LED. But the problem is
  that the colors are reversed: it should be red for wifi off and blue
  for wifi on, but it is rather the opposite!
