Hello, I first want to thank the Ubuntu devs, I've been a very long time Ubuntu user and appreciate what you guys do to make and keep it such a great distro. That being said, I too am affected by this bug on a fresh 17.04 install, I first noticed it after updating from 4.10.0-19 to 4.10.0-20, not to say -19 wasn't included but it's worth mentioning I never saw a crash when running -19. I have since updated via PPA to 4.11.0-041100rc5-generic with no change. Similar to the last comment on here by Nick about it crashing during scrolling in Chrome, I also have only seen crashes/freezes during Firefox scrolling. Music/sound will continue, video will play, however you lose all control over the system, caps lock doesn't respond, only a long-hold down of the power button seems to work. If anyone is interested in any log dumps or information from my system please let me know.

Just a note that you can also find the 4.8 kernel (image and headers) at http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D, and if you install the deb files from there, you don't need to enable the yakkety repos. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1677673 Title: System soft-freezes, BUG: unable to handle kernel NULL pointer dereference at 0018 in journalctl at gen8_ppgtt_alloc_page_directories.isra.38+0x115/0x250 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1677673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In my experience it was only after I added the Intel-specific drivers for my video card (in the Dell XPS 15 9560) that the crashing happened on 4.10.x.

This might also be related to https://bugs.freedesktop.org/show_bug.cgi?id=100516, which unfortunately isn't going to be fixed until kernel 4.12. ** Bug watch added: freedesktop.org Bugzilla #100516 https://bugs.freedesktop.org/show_bug.cgi?id=100516 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1677673 Title: System soft-freezes, BUG: unable to handle kernel NULL pointer dereference at 0018 in journalctl at gen8_ppgtt_alloc_page_directories.isra.38+0x115/0x250 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1677673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
