I did some further testing with following results: I can reestablish the correct suspend behavior by plugging in the drive, mounting, unmounting and unplugging the drive without powering down. This has to be done on exactly the same port, which triggered the misbehavior (other ports will not work).

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
