Hello, One of our 5.2.1R machines panics reproducibly when using mplayer on the following URL: rtsp://demand1.stream.aol.com/wb/gl/wbonline/real/wbmovies/catwoman/trailer/trailer_500.rm This was done on a remote X display. Although uname shows it as 5.2.1-RELEASE-p8, the linux module has been recompiled with the -p9 patch.
