The media_addon_server is constantly using 99,9–100% of the CPU.

ints output in the KDL:

int 14, enabled 1, handled 2201, unhandled 2202

Maybe ​#731 is connected?

Could you please try with a revision at least 33347 ? Clearly the driver initialization should now fail because the configured interrupt (0xff) is not valid. As the codec errors comes before installing the interrupt handler, I'm now wondering if this installation should better happen before cold resetting (as noticed at BG on Daniel's laptop).

Please try again with hrev39310 or newer. It should not help with the sound given the non configured device, but avoid troubles booting.
