Hi
I tried replacing
DRIVER_MODULE(uhso, uhub, uhso_driver, uhso_devclass, uhso_driver_loaded,
0);
with
DRIVER_MODULE_ORDERED(uhso, uhub, uhso_driver, uhso_devclass,
uhso_driver_loaded, 0, SI_ORDER_ANY);
but makes no difference..
Don't know if its relevant but with ucom debug on I get a message just
before crash in method ucom_close that it tries to close a connection that
has already been closed.
Hi Johannes,
Try the opposite:
DRIVER_MODULE_ORDERED(uhso, uhub, uhso_driver, uhso_devclass,
uhso_driver_loaded, 0, SI_ORDER_MIDDLE + 1);
Because I suspect that the "uhso_ifnet_unit" unrhdr is freed before the
"fake" detach is executed:
static int
uhso_driver_loaded(struct module *mod, int what, void *arg)
{
switch (what) {
case MOD_LOAD:
/* register our autoinstall handler */
uhso_etag = EVENTHANDLER_REGISTER(usb_dev_configured,
uhso_test_autoinst, NULL, EVENTHANDLER_PRI_ANY);
/* create our unit allocator for inet devs */
uhso_ifnet_unit = new_unrhdr(0, INT_MAX, NULL);
break;
case MOD_UNLOAD:
EVENTHANDLER_DEREGISTER(usb_dev_configured, uhso_etag);
delete_unrhdr(uhso_ifnet_unit);
break;
default:
return (EOPNOTSUPP);
}
return (0);
}
Alternativly set "uhso_ifnet_unit" to NULL and check this in probe and
attach!
