Still there is no need to add me back again, I will see the mail regardless. > On Sun, May 18, 2014 at 4:00 PM, Hans de Goede <[email protected]> wrote: >> Hi, >> >> On 05/16/2014 10:38 AM, Amit Kucheria wrote: >>> On Fri, May 16, 2014 at 1:17 PM, Hans de Goede <[email protected]> wrote: >>>> Hi, >>>> >>>> On 05/15/2014 08:56 PM, Amit Kucheria wrote: >>>>> On Thu, May 15, 2014 at 11:41 PM, Hans de Goede <[email protected]> >>>>> wrote: >>>>>> Hi, >>>>>> >>>>>> Thanks for the patch.

After that the screen1_output_* should no longer matter.

Does your phy chip also get hot (mine gets almost too hot to touch for a long period of time, but only if an ethernet cable is actually plugged in) ?
