Unfortunately, you haven't provided any useful information. Please have a read of http://www.freebsd.org/doc/en_US.ISO8859-1/articles/problem-reports/article.html In order to begin investigating this problem, we need to know: - the exact trap message (including the register contents) - the kernel backtrace - Details of your USB hardware (all the USB-related kernel probe messages) Since you state that the system begins dumping, you presumably have a crashdump and can easily extract the first two items above (see: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-gdb.html The last item will be in /var/log/messages. -- Peter Jeremy
