>From the posting: The reproduction case is almost always during copying large files that kswapd pegs at 100% CPU until the file is deleted or cache is dropped.
I believe I've seen this behaviour on earlier hardware than sandybridge, I can trigger it with good reliability using abocks image-writer to create a liveusb version of the GNOME3 isos (from gnome.org) however the hardware is question unfortunately died recently. Any large file copy operation should trigger it on sandybridge according to Mel though.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/808509 Title: SRU: Stop kswapd consuming 100% CPU when highest zone is small To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/808509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
