@mluypaert Thanks for the details.
Do you know whether the problem reproduces with any bowtie2 example that I could run for myself? I'm not familiar w/ it. Apparently there's a workaround for it, if you're willing to test: to disable NUMA balancing. This _might_ impact performance on some memory-intensive workloads that use memory on multiple NUMA nodes. If you previously used kernel versions 3.13.0-156 to 3.13.0-158 there should be no performance impact, as NUMA balancing was disabled in those versions to workaround a regression on 3.13.0-155. It was re-enabled by default on 3.13.0-159. You can disable NUMA balancing on a running system with this command: $ sudo sysctl -w kernel.numa_balancing=0 And then make the change persistent across reboots with this command: $ echo 'kernel.numa_balancing = 0' | sudo tee /etc/sysctl.d/99-numa- balancing.conf If you'd like to try that, please let us know how it goes in a few months maybe? :-) Thanks for your response anyway. cheers, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813018 Title: Kernel Oops - unable to handle kernel paging request; RIP is at wait_migrate_huge_page+0x51/0x70 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813018/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
