I.e, I did something right (emergency syncs do appear on the target computer), but most of dmesg doesn't manage to get across one meter of copper. That doesn't matter, though. It does look like pos>37 check may trigger some adverse sign effects or something. So pos<0 check - or blind luck? - gave me a good disk-saveable trace... There is more of the same later, of course. Much more. It looks the same, though.
