Hi all FreeBSD Hackers! :)
My FreeBSD auto reboot itself and I got this report by kgdb, but
actually I'm not a programmer. I don't know how to debug this error.
Could someone helps with fixing?
Thanx in advanced!

Do you use the nve driver? It has a known bug that causes a double
fault. Unfortunately kgdb doesn't know how to properly decode double
fault backtraces, so there isn't any more information about the cause.
If you are not using nve, can you try to reproduce and then see what DDB
says about the backtrace?
