The above looks like a kernel bug; if you could generate a stack trace, that would probably be the most helpful thing to send to the freebsd-current mailing list. You may want to make sure you're running the most recent 6.x code as bugs appear (and are fixed) with relative frequency. Make sure you follow that mailing list so you can get warnings of new features being added, etc, which can help minimize the risk of grabbing source from a bad day, or help you identify when a problem you're experiencing is already being worked on. It could be that re-installing will fix it, but it's more likely that the panic is a result of something about your system configuration (hardware, software) that isn't the case on a FreeBSD developer's system, so they haven't yet seen the bug (meaning that a report would be helpful).
