This would still be a flaky device or a kernel bug. Because the mentioned laptop-mode-tools version (1.71) brought in forced execution mode, so that it could apply proper power saving values. That's pretty much it. That does not result in read only rootfs because if it logically did, it'd be seen on every machine.
BTW, does Ubuntu have the systemd/udevd mount propagation fix included ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726930 Title: System fails to start (boot) on battery due to read-only root file- system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/laptop-mode-tools/+bug/1726930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
