Is this after suspend-to-OFF or OFF-while-idle?
I've experienced this with UART1 on SDP ES3.0, but according to
Rajendra it didn't happen on SDP ES3.1 (I don't currently have any
ES3.1 hardware) :(
Are all of yours ES3.1 ?
I haven't tracked it further since I only saw it on my SDP with UART1
and not on any other board.
