The kernel oops seems to happen when the laptop is left idle. It doesn't appear every time, so it is hard to reproduce. System is completely unresponsive after it and hard reboot is needed. I also observed identical freezes on Ubuntu 19.04, but never bothered to fill a bug report. I haven't observed this error on Ubuntu 18.04.
