Bug report attached, caught via ssh before restart. Fresh install ubuntu 19.10, new Dell Inspiron 5590. Happens randomly but usually within a few minutes of boot.
Edit: as per this thread: https://devtalk.nvidia.com/default/topic/1066854/ubuntu-18-04-freeze-gpu-fallen-off-the-bus disabling c-state control in the BIOS does not fix the problem
Setting power mizer mode to ‘prefer maximum performance’ does solve the problem, however drains the battery incredibly fast.
