For a full stack trace, add ddb to your kernel (see i386/conf/LINT). For a stack trace with gdb after the crash, you can enable crashdumps. At the very least, run configure with -g, and build a kernel with symbols. The run gdb on that kernel and do list *faulting_address. Eg, list *0xfffffc0000372e9c Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
