Sorry for the delay but I needed physical access to the host box. I upgraded XenServer to 7.0 (fully patched) and the problem persists.
I tried with kernel 4.9-rc3 and the issue is still there. I reverted to 4.4.0-45 and the issue disappears. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637666 Title: Heavy system slowdown with 4.8.0 kernel under XenServer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1637666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
