Finished the bisect between 3.6.10 and 3.7. Here's the log. The suspect patch
has an interesting name:
ahci: implement aggressive SATA device sleep support
I'll send email to the patch author too.
I should make it clear that this is not urgent for me, since 3.6.10 isn't
obsolete yet.

ahci: implement aggressive SATA device sleep support
Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal.
This feature enables an HBA and SATA storage device to enter the DevSleep
interface state, enabling lower power SATA-based systems.
Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as
soon as there are no commands outstanding to the device and the port
specific Device Sleep idle timer has expired. This enables autonomous
entry into the DevSleep interface state without waiting for software
in power sensitive systems.
This patch enables Aggressive Device Sleep only if both host controller
and device support it.
Tested on AMD reference board together with Device Sleep supported device
sample.
