Ben Harris, could you please test the latest upstream kernel available
from the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

** Description changed:

  On my Latitude 2110, the "dell_led" driver is useful for controlling the
  LED on the lid.  However, the driver doesn't load automatically on boot,
  and so /sys/class/leds/dell::lid doesn't exist.  I can load the module
  manually (with "sudo modprobe dell_led"), or I can put this line in
  /etc/modprobe.d/local-dell-led.conf:
  
  alias wmi:F6E4FE6E-909D-47CB-8BAB-C9F6F2F8D396 dell_led
  
  If I do the latter, then the module loads automatically at boot.
  
  I note that "modinfo dell_led" says:
  
  alias:          wmi:F6E4FE6E-909D-47cb-8BAB-C9F6F2F8D396
  
  Note that the "47cb" there is in lower case.  I suspect that this is the
  cause of the problem.
  
  I also note that the "hp_wmi" driver has a "wmi:" alias with lower-case
  letters in, so it may require a similar fix.

Title:
  [Dell Latitude 2110] dell_led driver does not auto-load (bad alias)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On my Latitude 2110, the "dell_led" driver is useful for controlling
  the LED on the lid.  However, the driver doesn't load automatically on
  boot, and so /sys/class/leds/dell::lid doesn't exist.  I can load the
  module manually (with "sudo modprobe dell_led"), or I can put this
  line in /etc/modprobe.d/local-dell-led.conf:

  alias wmi:F6E4FE6E-909D-47CB-8BAB-C9F6F2F8D396 dell_led

  If I do the latter, then the module loads automatically at boot.

  I note that "modinfo dell_led" says:

  alias:          wmi:F6E4FE6E-909D-47cb-8BAB-C9F6F2F8D396

  Note that the "47cb" there is in lower case.  I suspect that this is
  the cause of the problem.

  I also note that the "hp_wmi" driver has a "wmi:" alias with lower-
  case letters in, so it may require a similar fix.
