[Bug 1498387] Re: system hangs and CPU heats up in -29 but not -28


Nick Moffitt, thank you for reporting this and helping make Ubuntu
better. As per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-x-series-laptops/thinkpad-x240 an update to your
computer's buggy and outdated BIOS is available (2.33). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

  system hangs and CPU heats up in -29 but not -28

Status in linux package in Ubuntu:

Bug description:
  I filed this bug against linux-image-3.19.0-29-generic and hope that
  it has attached everything relevant.

  With linux-image-3.19.0-29-generic I can only run my thinkpad X240 for
  a few hours before I invariably trip over this bug and cause it to
  hang, heating up and driving the fan to full speed.  I never have this
  trouble when I select linux-image-3.19.0-28-generic.  Occasionally
  I'll reboot for updates (such as the recent network manager one) and
  forget to go down a build number, and I hit this again shortly after

  The screen remains in whatever state it was in, but I am unable to
  move the mouse or affect X with the keyboard (including trying to
  switch to a virtual console with Ctrl-Alt-F1).  Nothing suspicious
  shows up in kern.log after the reboot, but I tend to have to do a hard
  power-off to get back to a useful machine so the journal may not be
  fully checkpointed in time.
