<p class="MsoNormal">Greetings All<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am running dual linux on P1022RDK in AMP configuration. My memory partitioning is as below<o:p></o:p></p>

<p class="MsoNormal">My kernel command lines are for both cores <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have also partitioned my hardware among both cores and supplied appropriate “protected-sources” in mpic node of both DTS files. The problem is, I receive following warning continuously only on Core 0 console, but Core 1 is running smooth.
In following warnings source irqs are mostly which I have assigned to Core 1, but they are present in Core 0 mpic node “protected-sources” list, then why I am getting these messages.<o:p></o:p></p>
