So shall I assume the problem I have (hangs when moving mark points) is
caused solely by NPTL or is it 2.6.x the cause?

I can more or less easily disable NPTL; I'll have to recompile glibc, gcc,
wine, qt and all the apps which depend on qt such as kde. Those are the ones
which, AFAIK, use any NPTL (it's easy to find with prelink); a lengthy proccess,
but it can be done.

What would be harder for me is downgrading to 2.4.x, the performance is so
much better... and some features I would miss too. After all this is not
on an stand-alone vdr box, but a multi-purpose PC.

ATM I have both a 2.6 kernel and an nptl glibc system. The only app I've
ever had any problem with is vdr, last time was a plugin, and now I'm
facing those ugly hangs if I try to cut a recording...

Just tell me what to try, because I really have not a deep knowledge of
NPTL, if at all. I simply enabled it the first time I made a system
starting from a 2.6.x nptl enabled kernel. I even can't say if there is
any performance difference. After all I'm using UP, and I guess it'll
make more of a difference on SMP. I really don't know, though.
