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.
