I can't seem to install linux_kdump from ports:
===>  linux_kdump-1.5_2 does not build with the default linux base, use 
the package instead.
Which package? There is no linux_kdump package for "current".

If I use the normal kdump on the trace file produced by ktrace -i -d -p 
<pid> of the server, kdump itself dumps a core :-)

Cheers,
Ralph.
