Hello Matt.
I also remember when I was working with a baytrail system I had to attach
something to the LPC device in order to prevent this... Once I correctly set
the SIO under LPC the problem was gone.
In this case I don't have a board's schematic available to see what is attached
but I will start probing to try to find un-initialized hardware.
This board was created by autoport.
It's a Sandybridge based board and what I know is it has a Winbond w83627hg
attached to LPC which driver I already added under LPC in devicetree.
But this move didn't fixed this issue this time.
I will choose the Tianocore debug to try to see debug information from it.
Thank you,
Jose Trujillo.
