And the errors you got point to trouble with the UAS driver, specifically its command tagging, which was recently changed. So we need to find the crucial change. Before you bisect could you check whether the change that broke your device was: commit d285203cf647d7c97db3a1c33794315c9008593f Author: Christoph Hellwig <hch@xxxxxx> Date: Fri Jan 17 12:06:53 2014 +0100 scsi: add support for a blk-mq based I/O path.
