I have no clue. I don't have any problematic board, I just spotted commit when rebasing my kernel and suggested as a possible reason. I suggest that you contact all people involved in that commit (including relevant mailing lists) and explain the issue. Given that this commit is the fix, it's possible that it just uncovered another issue.
