[Bug 1349879] [NEW] powering off an usb3 device causes kernel to resume immediately after suspend

 

You have been subscribed to a public bug:

After powering off an usb3 disk (e.g. udisksctl power-off -b /dev/sdc)
the system immediately resumes after suspend. 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)
