>Description:
Opening an encrypted DVD with any DVD Player (Xine, Ogle, MPlayer) I get a system panic and I get an automatic reboot.
libdvdcss starts to decode .vob files and system panics depending on the DVD title: sometimes it crashes on the first file, sometimes after decoding three or four of them.
Here is the output of dmesg on my machine:
