Chris,

I downloaded that image you linked and loaded it onto a usb stick and
tested it that way (a little wary of direct installing it at first, it
not being a final release).. however it did use the local swap space on
the same drive and I was able to get kswapd0 to become active so I
assumed that would be a reasonable starter test... I wasn't able to
reproduce it with that release! the system did become slow when I drove
it out of memory... and I did see a few seconds of mouse stutter however
it never locked up permanently. Several of the applications I was using
to drive up memory usage became greyed out as they became temporarily
unresponsive but they returned to me and the system never locked up. I'm
a little sad about the performance low performance of the whole
situation however not locking up is a big plus and maybe if the
applications themselves never need data on a medium as slow as a usb2
key it will not hit the brick wall quite so much... on the other hand,
maybe the speed with which the ssd responded to data requests of
unswapped applications will cause the issue itself...

Another variable to consider might be that I did not enable the compiz
cube on the usb2 14.04 beta environment...  which maybe contributes to
the issue.

Anyway... I will reload the laptop shortly with the new code base and
see what happens. If I continue to be unable to reproduce it in
14.04...should I update any particular tags? you mentioned specific
actions based on "upstream" but no particular actions for 14.04 test
unless I missed it.

Thanks very much for the time and assistance.

Zach

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.
