Can you check where the error happened? If the error happened in ll_back_merge_fn via blk_rq_append_bio (EINVAL), it might be due to the following fix (which I put in the patch) : http://marc.info/?l=linux-scsi&m=122927795113939&w=2 This patch should do the right thing but this leads to more segments. But if your scsi host enables use_clustering, the error should not happen there. BTW, st driver in 2.6.27 can handle 16000 kB? > I will do some more tests tomorrow but your code looks really good.
