With boot parameter acpi_osi="!Windows 2012", this issue seems to disappear.
Test environment:
A06 / 12.04.4 + v3.11.0-{14, 15, 17, 20}
A06 / 12.04.4 + v3.12.{14, 16, 18}
A06 / 12.04.4 + v3.13.{8, 9, 10, 11}PS: This issue can be reproduced on those kernel versions without acpi_osi boot parameter. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288161 Title: [Dell Inspiron 7737] System reboots itself after powered off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1288161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
