*** This bug is a duplicate of bug 1674838 *** https://bugs.launchpad.net/bugs/1674838 I got this freeze again with 4.10.0-21-generic x8_64 kernel.

[Bug 1677491] Re: System freeze
Sorry, but checking my logs my stuck message has not "[ksmd:64]" at the end, but something different, I think "js" something. Right now I don't have any to put the exact string. I keep getting lockups with the 4.10 kernel series, I've updated to 4.10.0.20 now but I got one with 4.10.0.19. I ran 4.11 RC8 for a week and did not get the freeze. -- 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
[Bug 1677491] Re: System freeze
@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

I'm using the previous kernel now, 4.10.0-13-generic #15-Ubuntu, and after some hours I haven't seen the freeze. I saw it again using the kernel reported in this bug: linux-image-4.10.0-14-generic 4.10.0-14.16 I will run the 4.10.0-13 kernel a while longer to see if I see the freeze again. -- 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
[Bug 1677491] Re: System freeze
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
