["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Christian Iversen, could you please confirm this issue exists with the
latest development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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.

Title:
  Linux 3.2.0-26-generic (Ubuntu 12.04) only seeing 16GB/24GB RAM

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hello Ubuntu devs

  On my machine, I have 24GB ram, in the form of 6 x 4GB Kingston
  Hyper-X (3 kits with 2 blocks, exact model number KHX1333C9D3B1K2/8G).

  When booting Windows 7, I can see all 24GB without issue. However,
  when booting Linux, I only see 16GB total.

  For some odd reason, dmidecode only reports 4 DIMMs to be installed.
  Could this be related?
