We're clearly not testing the same configurations, as all your patches
either are not DT enabled or are for the non-multiplatform kernel
builds. I've tried porting your DMA bounce changes to the
multiplatform board-lager-reference.c file but that has not fixed
the issue for me.
This is the last log I have for looking into the issue:
