Well, it has all the info I need, but the results don't make me too happy. Everything I've checked seems consistent, and I don't know why the host stopped. The link TRBs are intact, the dequeue pointer for the endpoint was pointing to the transfer that timed out and it had the cycle bit set correctly, etc. Perhaps the no-op TRBs are really the issue. I'll have to take a look at the log again tomorrow. I posted the dmesg on pastebin if David wants to check it out as well: http://pastebin.com/a4AUpsL1 Can you send me the output of `sudo lspci -vvv -n`? Maybe we can just turn off scatter-gather for your host controller until we get a proper fix in that uses link TRBs instead of no-op TRBs.
