OK.  How the ***** do I get a *!@#$@$#% crash dump on current?  I
did a dumpon to enable the dumping, which appeared to work.  I then
did a savecore after the system came back up (but before any swapping
happened) and that seemed to work.  I then tried to use gdb to read
the core dump and got the following:

Needless to say, I'm somewhat frustrated as to what to do.  Ideas?
