Any module which returns an error on unload will cause the problem.
It's not specific to ipdivert.ko or ipfw.ko or anything else.
Relevant code section is:
static int
div_modevent(module_t mod, int type, void *unused)
{
int err = 0;
switch (type) {
[...]
case MOD_QUIESCE:
err = EPERM;
break;
[...]
}
return err;
}
Please note: Forced unload of ipdivert.ko works fine.
