hi Takashi, i installed the new module, and there are no problems yet. but as i am using it only a few hours, this does not really tell us much. but i have a question to you: which patches does the current module you made include? only the latest work_around_dma_issue.patch, or also all the previous patches? do the patches mutually exclude each other, or are they intended to be used together, or can they, but don't have to be used together?
