Zachary Dea, thank you for reporting this and helping make Ubuntu
better. Could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please just make a comment to this.

If reproducible, could you also 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:
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-3.14-rc8

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:
  [Asus X401A1] System slows/chugs/stutters then freezes when physical
  memory is low kswapd0

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Sometimes the mouse on my 13.10 laptop starts skipping, the system
  would become unresponsive, then completely lock up, and only a power
  off would restore it.

  Another time this started happening, I closed some apps right away and
  the system stayed alive. I was watching top while this happened and
  kswapd0 is active and my 2GB physical memory is low prior to the
  system grinding to a halt. I'm operating on a sata3 SSD, with 2GB swap
  space which was hardly used.
