I was playing a video in SMPlayer (mpv backend) on my laptop with Intel iGPU and GeForce GT 750M. Intel iGPU is the main (active) GPU, which is used for hardware acceleration of desktop and video decoding (which was not used at that time, as the video was VP9-coded, which is not supported by the iGPU). Nvidia driver is still loaded, as I use it on-demand for render offload (this was not used at the time of the incident).
I paused the video player (not stopped - the video image was still present), and closed the laptop lid. The system is configured to go into sleep mode when the lid is closed. At this point kernel OOPS happened, with the backtrace pointing to the nvidia-uvm module.
I’ve collected nvidia-bug-report after a reboot. I’m also attaching kernel log that contains the OOPS as it didn’t make it into nvidia-bug-report.
