There are no /sys/.../power/ files, because CONFIG_PM is disabled. This kernel does not freeze, so the debug output on unbinding is contained in the attached dmesg log. ** Attachment added: "dmesg from a corresponding 4.2 kernel, CONFIG_PM disabled" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1485057/+attachment/4469704/+files/dmesg-g-after-unbind.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1485057 Title: "lsusb -v" as root freezes the kernel on Acer ES1-111; also freeze on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1485057/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
