I installed updates to my 14.04 system about once a week, including any new kernel versions that came along (I always did "apt-get dist- upgrade"). In other words, there wasn't really one specific kernel version that I was using.
My dad's computer, which has pretty much the same hardware as mine (same model motherboard and CPU, I even bought the hardware for both computers at the same time), is still running 14.04 ("Ubuntu 14.04.5 LTS", according to the 'lsb_release' command). The kernel version that it currently reports (with 'uname -a') is: Linux wkst0 3.13.0-93-generic #140-Ubuntu SMP Mon Jul 18 21:21:05 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux As far as I can remember, his computer has been having the issue ever since I first installed 14.04 on it: if there are no USB media present upon shutdown, then the computer will successfully power off, but if any USB medium is still connected, then it will reboot. I refrained from upgrading his computer to 16.04 because under that release, the computer will reboot, instead of powering off, even without any USB media present. Now that I have at least a workaround for this issue, I was considering upgrading his computer after all, but I hadn't gotten around to it just yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618001 Title: My computer reboots instead of shutting down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1618001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
