Last friday I did a cvsup src/buildworld/buildkernel/installkernel/installworld/mergemaster

I noticed that sound skips when I play a mp3 with xmms and it also skips when I play dvds
(with mplayer, ogle or vlc). I have tried to recompile a kernel with apic disabled since I
had some performance issues with this enabled before 6.0-stable, but it didn't fix
anything. Does somebody have an idea of what change in the FreeBSD sources could be causing
this?
/me too, and I switched back to 6.0-RELEASE because of that. The problem
is the smart battery support that was merged shortly after 6.0-RELEASE.
Running wmbsdbatt the system freezes for 0.5s every 10s or so, this is
because wmbsdbatt is polling for the battery status. Disabling wmbsdbatt
everything was back to normal.
This can also be reproduced here with a acpiconf -i loop.
Other sources say, it's the thermal stuff thats blocking the OS, but for
me it's battery status. (Dell Inspiron 8600c, Pentium-M)

Yep, smart battery is definately the problem. The performance of my
laptop is back to normal when I remove the xfce4-battery-plugin.
acpiconf -i loop reproduces the problem for me too. So it looks like
there is something wrong in smart battery.
