[Bug 721896] Re: kswapd0 100% cpu usage


I've been seeing this issue for almost a year now on an Asus Ultrabook
(Core i5, 4GB RAM, SSD).  I installed and ran 13.04 until two weeks ago,
when I in-place upgraded to 13.10 (not a re-install).  I've been seeing
kswapd go crazy anywhere between weekly and daily, inevitably forcing a
reboot every time.

  kswapd0 100% cpu usage

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:
  After the running the latest ubuntu for at least 2 weeks, I've noticed that kswapd0 started using 100% CPU on one of my cores.
  However, I have enough of RAM and not using swap (Swap: 11876344k total,    62336k used).

  The only thing I can do to remove the problem is reboot the system.
  I'm using Ubuntu 10.04.1 LTS server version without any kernel modifications.
