At present RB5 runs against next-master are consistently throwing
warning messages (attached below with call trace) on "Memory manager not
clean during takedown". I can send full logs if required. However, the
runs are booting successfully so the logs are quite big. Tried running
with older dtb built, where these
warnings was not observed.
A bisect (full log below) identified this patch as
introducing the failure.
