I can tell you how to reproduce it easily: It has todo with the filesize. Try to copy a file which is larger than 4.X GB and the CPU usage bumps up to > 90%.
I can safely reproduce it. Leech a file (lets say 5 GB) - CPU usage 90%. Stop it - CPU usage normal. Restart it CPU usage 90%. Stop it and start smaller files - CPU usage normal. Move the same large file to an ext3 drive - CPU usage normal. Give it a try, I can safely reproduce this behavior for months now. -- mount.ntfs causes 100% CPU (iowait) https://bugs.launchpad.net/bugs/328352 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
