@Walter: On our forums exchanges, I missed that your "stuck" messages have "[ksmd:64]" at the end. I get that often also, but I also sometimes get "[qemu-system-x86:8549]" and "[qemu-system-x86:8552]".
I do not know what commits may or may not have been migrated back to kernel 4.10. At least for my issue, which we are not sure is the same as yours or not, these are the related commits: 3fe87967c536e828bf1ea14b3ec3827d1101152e mm: convert remove_migration_pte() to use page_vma_mapped_walk() 4b0ece6fa0167b22c004ff69e137dc94ee2e469e mm: migrate: fix remove_migration_pte() for ksm pages ace71a19cec5eb430207c3269d8a2683f0574306 mm: introduce page_vma_mapped_walk() d75450ff40df0199bf13dfb19f435519ff947138 mm: fix page_vma_mapped_walk() for ksm pages Because these events are so rare, I would suggest trying kernel 4.11-rc6 for an extended time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1677491 Title: System freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1677491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
