Where exactly does the logf output go to and how do I enable it? I
grepped for logf definitions, but I was rather confused by the hits.

I tried that some time ago and its still up at 10min.

I cleared the settings when I reinstalled rockbox after putting in the SSD.

Well, I was watching the buffering thread debugscreen once more and
found that the pcm buffer starves on track change. Is that the intended
behaviour, but without the wait for refill or should it never starve on
(expected) track change at all? If so, that would be a hint I guess.
