Comment 29 for bug 1269777

Running the mainline kernel for 3 hours now.

PCI(e) powermanagement is enabled and SATA is working in AHCI mode.
Started virtualbox, worked a lot with the system, ... no problems occured ...

Under the same conditions, the standard kernel 3.13.0-3-generic caused the system to freeze.

I' investigate further and keep the system running ...
