I'm adding support for a new 83xx board, the 8349E-mITX. For some

As soon as the mtmsr is executed, everything stops.
I also have this problem. Skipping address translation solves this problem. I also wonder, "why do we enable address translation at all?"\
There is a performance improvement from using address translation. You need to make sure you are setting up the BATs properly for your address map.
