And that's why it's missing the interesting bits (it seems to stop with
the read(0 expecting your input). If you type anything but return does it
survive?

That should never happen -

Better not dump the log to a file at all, serial might do better (I've
never tried to pipe some output through ssh but even that might work
better).

I'll try to reproduce this with my Lombard (which is newworld so it might
not show up). What ncurses version did it start happening with,
approximately (or around what date; I guess I can try to dig through the
buildd logs for clues then)? And what processor/video hw/disk does the
oldworld box have?
