If you want, you can check the handbook section on kernel debugging to see how to compile a kernel with debug symbols (config -g) and to setup a dump device via dumpdev in /etc/rc.conf. Then, when your computer boots up after a panic, it will save a copy of the kernel and a memory dump to /var/crash/kernel.0 and /var/crash/vmcore.0. You can then use the kernel debugger as root to get some simple info and send an e-mail with it to -hackers. You don't have to if you don't want to, though. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
