If this problem comes and goes as you switch kernel, this points to a possible kernel regression. In that case perhaps sssd is just the trigger rather than the buggy package. So I'll add the kernel package to this bug.
Or perhaps it's a latent bug in sssd that only triggers with the newer kernel that is still following spec. I guess we won't be able to tell without further investigation. In any case, letting the kernel team know seems appropriate. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags added: regression-update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746806 Title: sssd appears to crash AWS c5 and m5 instances, cause 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1746806/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
