I have exactly the same problem with Lubuntu 13.10, 64 bit. When i copy a big file from hard drive to USB stick, the system gets laggy and iotop shows that kswapd0 periodically eats 99.9% of IO.
Turing of hugepages (http://lwn.net/Articles/467328/) and adjusting dirty_background_bytes / dirty_bytes (http://lwn.net/Articles/572911/) did not solve the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1267648 Title: Copying large amount of files to USB stick makes system laggy or even freeze/hang (temporary) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1267648/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
