I installed 4.15.0-56 from -proposed and ran some CPU stress tests and everything was stable and no problems detected.
The kernel was also installed onto a few machines from the production hadoop cluster which experienced extremely high cpu load, and the kernel is stable, with no CPU lockups in sight. Since this is also an upstream -stable patch, and we have good test results from the hadoop cluster which was suffering the issue, I am happy to mark this as verified. ** Tags removed: verification-needed-bionic ** Tags added: verification-done-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836971 Title: sched: Prevent CPU lockups when task groups take longer than the period To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1836971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
