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

Eric Detheridge, at your earliest convenience, could you please test the
latest upstream kernel available from the very top line at the top of
the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
(the release names are irrelevant for testing, and please do not test
the daily folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  [147461.082140] BUG: soft lockup - CPU#3 stuck for 22s!
  [khugepaged:40]

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Happened right after a YouTube video of music finished. mouse and
  keyboard locked up but system monitor applet kept running showing full
  usage of all four cpu cores. tried to log on remotely but this was
  very slow. used htop to see what was using cpu but it showed only
  three cores active with boinc work units as usual conflicting with the
  system monitor applet. eventually htop stopped working. could not find
  excess cpu usage with top either. eventually the system monitor applet
  showed only 50% cpu usage with lots of io waiting. eventually did soft
  reset. cpu is overclocked but has run stable with heavy boinc usage
  for weeks.
