Several panics during unload of netgraph related klds

[Martin Blapp]

Hi all,

I've just noticed that I cannot unload

 8    1 0xc4226000 4000     if_tap.ko   (panics)
 9    3 0xc4350000 12000    netgraph.ko (unloads, but is still there)
10    1 0xc4222000 4000     ng_ether.ko (reports busy)
11    1 0xc41a7000 5000     ng_bridge.ko (works)
12    1 0xc421e000 4000     ng_socket.ko (reports busy)

A bogus message is also available:

kernel: kldunload: attempt to unload file that was loaded by the kernel

If a network module is loaded before these module,
the system panics if one tries to unload the kernel module.

Unfortunatly I cannot provide panic dumps, something in
savecore seems broken since yesterday.
