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

Ilya A. Potapov, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, 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 (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine 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:
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-v3.12

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

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:
  system hang few minutes after unpluggin AC

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Just few minutes after unplugging AC Adapter my laptop "hangs". Same behaviour exists when i just boot laptop without AC Power.
  System hangs on all recent 3.2.x linux kernels from precise repository, but all is normal on 2.6.38-11-generic.

  At first mouse is working and i can even move windows, while all window's content is unresponsible. I can even switch to another terminal with ctrl+alt+Fx and then:
  1) if i not logged in there, terminal hangs after typing username and pressing enter
  2) if i logged in there, i can execute some commands (i can not exactly say which, but i can run htop and ls)

  After few minutes system hangs at all and only option is to reset
  note.

  It is interesting, that if system hangs after unplugging AC Adapter,
  it "unhangs" after pluging adapter back.

  I looked through all logs with appropriate modification date in
  /var/log/* but found nothing interesting.

  I just do not know what additional information i can provide, but i
  will kindly provide any info on request.
