I spent a bit of time looking at the alpha patch and could not spot a
typo, it looked OK to me. I was worried for a bit that virt_to_phys()
vs __pa() were different, but I could not find a difference.
Suggest testing the same branch with the alpha patch reverted just to
rule out any issue in the core code. If it reproduces suggest to
bisect Leon's branch.
Thanks,
Jason
