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. Kevin
