Same here. I have this problem since I updated to 15.04 that goes with the 3.19 kernels. With the previous series of kernels 3.16 it was working just fine.
My laptop is a sony vaio vgn-cs11z. In my case failing to sleep has nothing to do with external devices, it happens anyways. Also after the failed sleep I cannot shutdown properly. I confirm that I can still hard shut off everything with "reboot -f" or "poweroff -f". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441253 Title: hanging suspend job prevents shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1441253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
