We need some stack information to help us determine the cause of the CPU spikes.
1. Download the attached dstack script to your home directory. 2. Log in to a virtual terminal (Ctrl+Alt+F1), and switch back (Ctrl+Alt+F7) 3. When the spike happens, switch to Ctrl+Alt+F1 and run this: sudo -s sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt sh ./dstack bluetoothd >> stacks.txt (yes, five times) 4. Attach the resulting stacks.txt to this bug. ** Attachment added: "dstack" https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1717796/+attachment/4951926/+files/dstack ** Changed in: bluez (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717796 Title: Bluetoothd fills 100% CPU when bluetooth keyboard goes in idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1717796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
