I have too observed this behavior with disk-heavy processes, and also having home encrypted. The troublesome part is that it has come and gone since at least natty (see my report #665211), without any conditions (that I can identify) changing. After several months of happiness, I'm again intermittently getting it in another computer with the 'deluged' process.
My old report was marked invalid since it apparently went away and I couldn't really narrow down the cause. With this I mean that I wouldn't be totally confident after a few tests that the bug is fixed (although I hope so!), without having identified the cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925309 Title: unkillable process consuming 100% cpu time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925309/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
