@Tim, managed to get some overnight testing on this kernel, results are very good:
Did 1000 x test cycles, each copying ~795MB of data (~7 hours of soak testing), no lock-ups on a SNB laptop with 4GB memory. Also re-ran with 500 x test cycles with 2GB memory (as this *really* exercises the bug). My test script (which contains portions of the ubiquity copying script which originally tripped this bug) is attached. Testing - run script to copy data from one ext4 partition to another. /dev/sda3, ext4, source, containing ~795MB of files from the Natty installer /dev/sda4, ext4, destination Summary: Exhaustive testing passed. ** Attachment added: "Test script to exercise bug" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/808509/+attachment/2205312/+files/ubiquity.nousb.simple -- 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
