Thread: kswapd0 maxing CPU, kernel 3.14

  1. #1

    Default kswapd0 maxing CPU, kernel 3.14

    Using a laptop, AMD 64 dual core, 3.5 GiB available memory, typically 1.5 to 2.5 in use with no or low swap usage (2 GiB available), running KDE with multiple applications open.

    I am following Tumbleweed with multiversion kernel. Currently have kernel-desktop (X86_64) 3.11.10-7.1, 3.14.0-23.6.gfa168d7, and 3.14.1-24.1.geafcebd

    I've noticed with the 3.14 kernels and a late 3.13 one, with the above usage, that kswapd0 pegs a CPU for extended periods, as reported by KSysGuard. Actual swap usage doesn't change. Logging out of KDE and using a terminal with top has no problems. Kernel 3.11.10 has no problems.

    This appears to be in the form of a bug report. Did I find the right forum?

    I think you would do well to discuss your findings on openSUSE's "Factory" mailing list where the devs expect issues with "Tumbleweed" included in the title/subject line. The Tumbleweed maintainer Greg K-H will most likely respond there. They will advise if a Bug Report needs to be raised on bugzilla.

    You can also peruse the Factory ML Archive here: http://lists.opensuse.org/opensuse-factory/

    I forgot to mention the advantage that Greg is also a kernel developer.
