[Bug 672793] Re: system is wedged, new ssh connections are closed instantly and console is black with a mouse but does not accept keyboard input


Greg Dahlman, 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) 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:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

  system is wedged, new ssh connections are closed instantly and console
  is black with a mouse but does not accept keyboard input

Status in “linux” package in Ubuntu:

Bug description:
  This started happening on Thursday November 4th.

  This only seems to happen when the host is idle at the console.
  although a KVM instance was actively being used on one of the effected

  The system will hang and will be unresponsive to any keyboard input
  although you can see a mouse cursor.

  ssh connections are closed as if they were filtered.

  ctl-alt F* does not work

  oddly enough a windows KVM host was still responsive.

  A coworker is also having this issue with his machine which is running
  vm's in virtualbox

  Both systems are Dell Optiplex 960s

  The system did not respond to a soft shutdown with the power button

  We were forced to reboot by using the NMI shutdown by holding the
  power button down.

  Unfortunately it appears that syslog just quit logging and there are
  no errors in any log files.

  We both did run updates and here is the entry of what was updated that
  day on my machine.
