Thank you, Joseph! I did test upstream at v4.13-rcr4 as you suggested. Same complaints. I tried v4.13-rcr4 "lowlatency" as well, same complaints.
What seems strange to me is that I don't think I was getting these complaints under 16.04 LTS Desktop with Studio (ie lowlatency)/LAMP/ZoneMinder overlays. This same machine, same H/W, was subject to intense scrutiny under 16.04 schema as described for at least 3 months after installing the NEC/Renasas 27xxx2 based Startech card. Very hard to believe I didn't pull a DMESG in all that time. But stranger things have happened. Will try to follow on this report as suggested. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710548 Title: Nec/Renasas 27xxx2 May also need Quirk in 17.04, no problem in 16.04?
