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

Brian Candler, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel 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-v3.12-rc3

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:
  Lenovo Thinkpad x100e freezes when X blanks screen

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  [Moved from #535653. I have no problem with X starting up, but only
  when X blanks screen]

  Machine is a Lenovo Thinkpad X100e model NTS5EUK:
  AMD Turion(tm) Neo X2 Dual Core Processor L625 stepping 02
  + 2GB RAM, internal WLAN (realtek) and WWAN (Gobi 2000) cards. BIOS version reported is 1.21. Originally I had turned on the AMD virtualisation extensions in the BIOS, but I've now switched this back, so BIOS is at defaults including

      Config > CPU > AMD V(TM) Technology = Disabled
      Security > Memory Protection > Exection Protection = Enabled

  In #535653 I reported this problem with amd64, but I've now installed
  i386 from scratch with exactly the same behaviour.

  The laptop is connected to an Ethernet LAN and a USB CD-ROM. I have
  not configured wireless at all.

  I can reproduce the problem as follows.
  * Install Lucid 10.4 desktop i386 from CD
  * apt-get update && apt-get dist-upgrade && apt-get install openssh-server
  * echo "options radeon modeset=0" > /etc/modprobe.d/radeon-kms.conf
  * cat >/etc/X11/xorg.conf
      Section "ServerFlags"
      Option "BlankTime" "1"
      EndSection
  * reboot, let it come up to the gdm screen, then don't touch it

  From another machine on the same LAN, copy a large file using scp, e.g.
      scp ubuntu-10.04-desktop-i386.iso brian@x.x.x.x:/var/tmp/

  You can also periodically check the network health from another window:
      while date && ssh brian@x.x.x.x hostname; do sleep 9; done

  What happens is: after 1 minute the X screen blanks. At this very
  instant, the laptop network connection freezes: the scp session
  stalls, and the laptop won't respond to ping. Moving the trackpoint,
  the screen comes back to life, but then the laptop is in a very
  fragile state and soon crashes. For example, pressing Ctrl-Alt-F1
  usually freezes it instantly. Selecting "reboot" from the power menu
  will start the reboot process, but leave it frozen on a blank purple
  screen (possibly at the point of changing video mode again?). At this
  point the machine has to be hard powered off by pressing and holding
  the power button.

  Extra data points:
  * Login, open a terminal and type "xset s noblank" then repeat the test: the machine does NOT freeze. (I get a big "X" and a chequerboard pattern instead of the screen being fully blanked).

  I think this all suggests that the X blanking is the culprit, although
  it's not clear why the machine should stop talking to ethernet
  instantly but continue along in a crippled state otherwise.
  (Interrupts?)

  I did previous testing with amd64, recorded under #535653, but I have not repeated these tests with i386 yet. I found that:
  * leaving the screen in text mode (via ctrl-alt-F1) does not crash, even if the text mode screen blanks
  * installing fglrx driver didn't make a difference

  Also, I was able to reproduce the problem on the train this morning on
  battery. All of the rest of my tests have been with mains connected.

  There are two warning messages which flash up while the machine boots,
  I think they are these two lines from dmesg:

  [   11.310661] shpchp 0000:00:01.0: Cannot reserve MMIO region
  [   11.764446] thinkpad_acpi: Not yet supported ThinkPad detected!
