This does not happen, if I umount the device and disconnect it. Usb devices < 3.0 seem not to be affected. How to reproduce: 1) plug an usb3 device to an usb3 port and mount it 2) umount it 3) power it off: udisksctl power-off -b /dev/sdX 4) suspend: (e.g. echo mem > /sys/power/state) result: system suspends and immediately resumes Package: udisks2 (2.1.3-1) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349879/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
