It sounds like the upstream 4.4 kernel does not have the bug per comments #10 and #12.
It appears this bug may be caused by a SAUCE patch that is not in the upstream kernel. To confirm that, can you test the upstream 4.4.44 kernel, which is what 4.4.0-64.85 is based on? If the bug does not exist in 4.4.44, we can perform a kernel bisect with the Ubuntu kernels to find that SAUCE commit that introduced this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646277 Title: Xenial server 16.04.x will have a black screen after PXE installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1646277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
