Sure, will do, thanks!

That's a wonderful question. I actually found a screenshot I took on
the 14th October(!) with one of these traces. I don't know the exact
kernel version, but since I've been running weekly release candidates
for years, it shouldn't be hard to pinpoint, if strictly needed. Since
the trace seemed informative and I haven't noticed any problems, I was
kind of hoping it would solve itself in time. I guess my patience
lasted 6 months. :)

Kind regards,
Rui
