Same symptoms here with a Lenovo IdeaPad Z360. Booting on battery only works about 33% of the time, but once it starts, everything is working fine. On AC power it boots without any problems.
No proprietary drivers here; NVidia GPU disabled @ bios. Seems like most of Lenovos recent IdeaPads are affected... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775950 Title: fixing recursive fault but reboot is needed! upon boot without AC (only battery) -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
