I seriously doubt that a total revert is the correct answer to this
problem. Can you pick up the discussion with Huang on the mailing
list, or at least explain what the actual root cause is? Have you been
going through some private communication on this issue? A proper
bugfix with an identified issue is preferable to a blind revert.

Huang, is the DMA patch you sent related, or is it a totally different bug?
