Finished the bisect between 3.6.10 and 3.7. Here's the log. The suspect patch has an interesting name: |

| 3 |
ahci: implement aggressive SATA device sleep support |
| 4 |
|
| 5 |
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 |
| 46 |
|
| 47 |
Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal. |
| 48 |
This feature enables an HBA and SATA storage device to enter the DevSleep |
| 49 |
interface state, enabling lower power SATA-based systems. |
| 50 |
|
| 51 |
Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as |
| 52 |
soon as there are no commands outstanding to the device and the port |
| 53 |
specific Device Sleep idle timer has expired. This enables autonomous |
| 54 |
entry into the DevSleep interface state without waiting for software |
| 55 |
in power sensitive systems. |
| 56 |
|
| 57 |
This patch enables Aggressive Device Sleep only if both host controller |
| 58 |
and device support it. |
| 59 |
|
| 60 |
Tested on AMD reference board together with Device Sleep supported device |
| 61 |
sample. |
