Okay. Are you absolutely sure, that the device tree matches with the
cell configuration? I wonder why the kernel tries to access virtual (!)
address 0x1388, which apparently has no mapping. In case everything is
configured correctly, then we have here some issue with the kernel, and
you should debug in this direction.

Please provide more context. Does this happen in the root or
non-root cell?
