Is this a regression? Can you find a working kernel?
Comment 2 zhaodan 2014-09-19 06:56:33 UTC 
I don't confirm it is a regression and I don't find the good kernel.
Because the August 15 kernel also bad and the BSW platform can't work on the July kernel.During find the good kernel, the kernel can't work normally always,so I can't find the good kernel.
Comment 3 Ville Syrjala 2014-12-18 11:31:01 UTC 
Did you perhaps have something else using pipe B already?

If not, please test again with a more recent kernel.

If I understand that correctly, this works now. Closing.
