Or maybe this has something to do with the vdpau support that was added to flash with the last update and that others reported as possibly not working properly on FreeBSD... If you did rebuild nvidia try mv.ing /compat/linux/usr/lib/libvdpau.so.1 away temporarily and see if that fixes the panics, if yes its probably an nvidia issue. And even if not I guess you need to collect a backtrace or at least a textdump of the panic, see here about how to get a dump: http://www.freebsd.org/doc/en/books/developers-handbook/book.html#KERNELDEBUG-OBTAIN If the dumping/savecore/crashinfo script worked you should get a new /var/crash/core.txt.X file with the backtrace (among other things) after the next boot. Good luck, :) Juergen
