[881346.853394] BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 [881346.853465] IP: gen8_ppgtt_alloc_page_directories.isra.16+0xd9/0x280 [i915] But it's like once a week, i notice that it only happens (but not always) when i get full memory and it starts to swap (and that's like once a week on 16GB of ram, it gets full because of those electron app that after a while use even 1.5GB/app, so periodically i restart them to maintain low (under 8GB) memory usage. Before (but probably still) on KDE whenever i got my memory full the plasma will just totally freeze until some app doesn't crash with OOM, but that takes a while until the swap is filled up or i kill some apps from console/ssh. And other apps (like music playback, ssh) still works after i915 crash. ** Attachment added: "kernelbug.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680904/+attachment/4908627/+files/kernelbug.txt -- 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
