** Description changed:

- My laptop I have loaded with 13.10 and right off the bat I noticed that
- sometimes out of the blue the mouse would start skipping, the system
- would become unresponsive, and then completely lock up, only a power off
- would restore it. The next time I caught it and closed some apps right
- away and the system stayed alive, but following me opening more the
- behavior was reproduced. I started watching top while this happened and
- I see kswapd0 is active and my physical memory (only 2GB) is low prior
- to the system grinding to a halt. I'm operating an a sata3 ssd for disk
- and I have 2GB of swap space which was hardly used... bandwidth is
- lightning as you would expect so it's not like I have a slow swap space
- that I'm just waiting for (besides, it doesn't seem to ever wake up).
+ Sometimes the mouse on my 13.10 laptop starts skipping, the system would

- ... seems to have a number of users toward the end complaining of the
- same symptoms and they were directed to file something here, however I
- didn't see any responses back indicating that it had been done, and as
- my system is fully up to date I have to assume this issue remains.

- Thanks,

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

Status in “linux” package in Ubuntu:
  Confirmed

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.
