panic — bring down system on fatal error

       The  panic()  and  vpanic() functions terminate the running system.  The message fmt is a printf(3) style
       format string.  The message is printed to the console and the location panicstr is set to the address  of
       the message text for retrieval from the OS core dump.

       If  the kernel debugger is installed control is passed to it, otherwise an attempt to save a core dump of
       the OS to a configured dump device is made.

       If panic() is called twice (from the disk sync routines, for example)  the  system  is  rebooted  without
       syncing the disks.
