 Commenting out this define
 
     #if __FreeBSD_version >= 700031
     #define USE_SX_LOCK  1
     #endif
 
 in oss-v4.0-build1015-src-bsd/kernel/OS/FreeBSD/wrapper/bsddefs.h and
 reinstalling the port avoids the panic. As a result, KDE system sounds play
 normally and mplayer works, too. So it looks like there's something wrong with
 the way OSS uses sx locks. I'll report this on the 4Front forum.
