This is not btrfs issue, just tested that. Live cd of Ubuntu 11.04 boots on 512 machine and runs most of time with zero swap usage. On the same machine lubuntu 11.10 and xubuntu 11.10 boot up with 100+ mb of swap used, on a system without any btrfs partition.
But weird thing is that I've upgraded Xubuntu 11.04 on that same machine to Xubuntu 11.10 and swap usage is quite normal. Currently I can't test it on a later kernel, I'll try to do it later this week. ** Summary changed: - Lubuntu 11.10 beta2 swaps too much + Lubuntu 11.10 swaps too much -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/863552 Title: Lubuntu 11.10 swaps too much To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/863552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
