Summary: Resume does not power up the second drive.
Product: ACPI
Version: 2.5
Kernel Version: 3.15+

Severity: normal

I have Lenovo T520 with one SSD and one SATA drive.
I tried to upgrade to Linux 4.0 and found that after suspend and resume I can't
access the second (SATA) drive. I see I/O errors.
Both drives have bios encryption enabled.
I did a bisect and found that the following patch causes the issue:
commit 5d5132059a1f652de9dc2d62a8ff15561e648d11

ACPI / ATA: Add hotplug contexts to ACPI companions of SATA devices
Modify the SATA subsystem to add hotplug contexts to ACPI companions
of SATA devices and ports instead of registering special ACPI dock
operations using register_hotplug_dock_device().
That change will allow the entire code handling those special ACPI
dock operations to be dropped in the next commit.

What other information would you need. I'm not sure what debug info to provide.
