Description Darren Hart 2013-05-23 15:27:06 UTC 
In order to get the audio device to work it is necessary to disable MSI interrupts in the OS. The firmware appears to have them disabled, so the OS should not be attempting to use them. The OS read of the config space however indicates they are enabled. We need to identify where this is happening - or enable them deliberately in the config space from firmware.

MinnowBoard v1 has reached new feature EOL, FW development is done as are new hardware features.  If you feel EXCEEDINGLY strongly about an issue please re-open it for discussion but be aware that we are recommending individuals migrate to the MAX platform.
