Since the reporter says that reverting this commit fixes the problem, it must have caused the problem. For the benefit of those on linux-scsi who are just tuning into this report, the original mail is at http://lkml.org/lkml/2007/11/13/250 and the report that reverting this commit fixes it is a followup to it. I've stared at the patch, trying to figure out what's wrong. The only thing which makes any sense to me is that a request comes in, tagged as REQ_TYPE_FS. Later, it becomes REQ_TYPE_BLOCK_PC. This would have caused us to call sr_done() before the patch, and after the patch, we would not call sr_done(). Further eyes are welcome. James has suggested that the problem may be that ide-scsi does just this. Thomas, can you confirm whether or not you were using ide-scsi? -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
