I have encountered the same panic on one of my machines running HAMMER
here:

Unfortunately no crash dump :(  The machine is running HEAD from Tue Sep
30 11:47:27 CEST 2008.  It is a Intel C2D 3GHz with 2GB RAM running a
SMP kernel.  The fs layout is as follows:

ROOT                              292G    60G   232G    21%    /

The machine performed a pkgsrc "cvs update" before it crashed.  If more
information is needed, I'll provide it.  After the reboot kern.maxvnodes
is 129055 if that matters ...
