[Bug 1037718] Re: 8086:4222 [Dell Precision M4300] Intel wifi led is off after resuming from suspend


Cas, thank you for testing mainline kernel v3.13-rc3. Unfortunately,
there are issues with both your downstream and upstream report.

First, while you tested a more recent mainline kernel, the most recent
one is http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc5-trusty/ .
Could you please test this and advise to the results?

As well, if reproducible in this, given this is a wifi related issue,
could you please the latest development release from the linux-next tree
via http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/ ?

Thank you for your understanding.

  8086:4222 [Dell Precision M4300] Intel wifi led is off after resuming
  from suspend

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:
  I have set the wifi "options iwlegacy led_mode=1" in
  /etc/modprobe.d/wlan.conf to stop the led blinking, which works as
  expected. The problem I have found is that if I suspend the laptop
  then upon resuming the wifi led is permanently off yet the wifi still
  works properly.

  Also it is not just suspend that affects the LED, disabling wifi from
  network menu or using the hardware wifi switch on the laptop results
  it the same problem that the LED is permanently off after turning wifi
  back on.

  This is regression going from kernel 2.6.38 (Natty) to 2.6.39

  Note: I am not sure if it was clear enough that when the led is set to
  blinking there is no issue with it being off upon resume etc.

  WORKAROUND: To get the LED back on without rebooting reload the module:
  rmmod iwl3945 && modprobe iwl3945

  WORKAROUND: For the suspend issue is to add to /etc/pm/config.d/modules :
