>Description:
	Kernel often panics with "free vnode isn't" panic.  This first
	started around 1.3K.  I didn't report it because my 1.3K kernel
	was not compiled with egcs, the current compiler at that time.
	Finally, after getting upgraded to 1.4 and recompiling with 
	egcs I still have the problem.  On my system, I have not seen
	an uptime of more that about 2 days.  It normally panics during
	running of the daily script.
>How-To-Repeat:
	Big builds (kernel compiles) or daily script that does a find
	can cause it.  I have not found a reliable way to generate
	it.
>Fix:
	I have no fix.  I do have several kernel dumps and would be
	willing for someone who is investigating to use gdb on them.
