resume and free vnode isn't.

Dependably my Dell D800 will suspend, resume and then sometime later
crash with the following epitaph:

panic: getnewvnode: free vnode isn't
at line 738 in file ../../../kern/vfs_subr.c

The crash dump has the trace included below, but I believe the
corruption to be coming from the suspend/resume process not the
filesystem operation that panic's the machine.  The panic will occur a
random amount of time after the suspend/resume ... sometimes many
hours.  The nightly periodic scripts are almost certain to cause it.
