I think I had the same problem on zesty. It started occurring AFTER I used nvidia-settings to switch to integrated intel graphics on a Dell XPS-15 9560 (GTX1050) and completely uninstalled nvidia drivers to get back to a working laptop.
Indeed it seems to happen while using chromium. My machine was nog completely crashed though, I could still ssh into it. But restarting X or even rebooting was impossible, I did need to force power off. I installed the upstream kernel, to be precise: linux- image-4.12.0-041200rc3-generic_4.12.0-041200rc3.201705282131_amd64.deb For about a day now the laptop is very stable and VERY cool. No fan noise and battery usage seems to be much better than ever before without nvidia drivers. Can't wait to get this kernel fully supported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1680904 Title: zesty unable to handle kernel NULL pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680904/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
