I had to dig to find this: but Horia had said[1] that the HW was
specified to use lo-hi and I think we ended up changing to that for this
commit based on his feedback. This is also mentioned in the commit message.

Besides that, it looks like we are hitting an undefined instruction. So
my best guess is that we are somehow now calling a proper 64bit read
when we should be calling two 32-bit reads.

Fabio, can you send your configuration?
