That's because what I instructed in #15 makes laptop-mode-tools ineffective to USB hotplug events. Not something that a user would want.
As I see from the reports, this is what I think is happening. 1) Users have some combination of usb devices, getting hotplugged upon discovery. 2) Step 1 results in early invocation of LMT. 3) Which further results in file systems getting ro mounted. This step is still erratic and I have no clue what the calling parent is, to this ro mount. For users who've confirmed that #15 in the workaround works. Can you please apply the workaround, successfully boot, then change back the changes to its original, and then hotplug a USB device ? This will trigger the same chain of events, just that they'll be triggered upon full boot. Which should give us some insight into what may actually be behaving erratic. -- 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 firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
