Ubuntu Version : 18.04 Kernel : 4.15.0-45-generic

I don't know the reason but suddenly bluetooth doesn't work in my ubuntu machine. As you see the syslog, it's repeating unlimtedely. It's happening every 1~2 seconds. It's crazy now.

It worked fine last week. but today I realized that it has problem now.

Can anyone help?

I solved the issue from similar question in Bluetooth not working at all after I made some changes to pair with PS3 joystick

  • Just shutdown the system: sudo shutdown -h now
  • unplug every connected Cable like power, HDMI, CAT5.E, even Keyboard & Mouse USB
  • some seconds later, plug it again, and eventually it worked

I answer my question for whom experiences similar issue

I solved the issue by updating my kernel to the latest (4.19 to 5.9), shutting down, unplugging all USB devices, rebooting, and plugging the devices in one by one.
