Public bug reported:

So similarly to bug
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579917, I am also
not able to get into pc10, as described there.

I am using a sata drive, and after setting min_power to
/sys/class/scsi_host/*/link_power_management_policy still does not get
me into any states lower than pc03.

Following these links -- without testing the patched kernel (Setting min_power gets me to pc03, but not any further)
