Subject: Re: usb 3.0 hard drive doesn't work

This is probably a known issue.  Other Western Digital hard drives had
issues with the Link PM feature that went into 3.5.  Can you please test
with this branch:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git -b for-usb-linus-pending

In particular, I think this patch will help you, if you want to just try
that:
