I have been running ~kernel-ppa/mainline/v4.12-rc2 for over 5 days now with neither screen blinking nor power loss.
I had also tried the vanilla 4.11.2 kernel from kernel.org, which did have the problem. It seems like a fix occurred sometime between 4.11.2 and 4.12-rc2. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1693544 Title: power loss with kernels newer than 4.1 in Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1693544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
