Tried it, still broken.

But my kernel config had memory compaction (that turned on page migration) and
bounce buffers. I do not remember why I found them necessary but I will try

First, I found out that both the problematic alphas had memory compaction and
page migration and bounce buffers turned on, and working alphas had them off.
Next, turing off these options makes the problematic alphas work.
