Cas, the issue you are reporting is an upstream one. Could you please
report this problem through the appropriate channel by following the
instructions _verbatim_ at
https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream
?

Please provide a direct URL to your post once you have made it so that
it may be tracked.

BTW, nicely done investigating the upstream commits and the WORKAROUND.

Thank you for your understanding.

** Changed in: linux (Ubuntu)
       Status: Confirmed => Triaged

** Summary changed:

- Bluetooth LED on Dell laptop permanently on
+ [Dell Precision M4300] Bluetooth LED permanently on

** Description changed:

  When switching off bluetooth the LED used to also turn off, I re-tested
  quickly with Natty to confirm this, but for at least the last two
  releases the LED is stubbornly staying on all the time.
  
- There are two similar expired bugs #1094590 and #178872
+ I have identified the commit specific to Dell laptops that broke this
+ and quite coincidentally this same commit was just reverted on the next
+ branch only a few days ago. It's not all good however as the companion
+ commits replace a laptop blacklist with a whitelist meaning it currently
+ only works with Latitude models so I have to see if I can get Precision
+ models also included.
+ 
+ The commit that resulted in this issue was introduced in 3.5 kernel as
+ "dell-laptop: Remove rfkill code"[1]
+ 
+ I have built and tested the linux next branch code with the revert
+ commit [2] and then modify the "Latitude" product string commit [3] to
+ "Precision" and the bluetooth LED is now switching off as it should do.

Title:
  [Dell Precision M4300] Bluetooth LED permanently on

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  When switching off bluetooth the LED used to also turn off, I re-
  tested quickly with Natty to confirm this, but for at least the last
  two releases the LED is stubbornly staying on all the time.

  I have identified the commit specific to Dell laptops that broke this
  and quite coincidentally this same commit was just reverted on the
  next branch only a few days ago. It's not all good however as the
  companion commits replace a laptop blacklist with a whitelist meaning
  it currently only works with Latitude models so I have to see if I can
  get Precision models also included.

  The commit that resulted in this issue was introduced in 3.5 kernel as
  "dell-laptop: Remove rfkill code"[1]

  I have built and tested the linux next branch code with the revert
  commit [2] and then modify the "Latitude" product string commit [3] to
  "Precision" and the bluetooth LED is now switching off as it should
  do.
