Comment 1 Josh Boyer 2012-04-17 16:42:46 EDT
If you can recreate this without the external modules loaded, that would be appreciated.
Comment 2 Andy Freeland 2012-04-17 16:54:58 EDT
I can try running without tp_smapi, but I have no idea what caused it.
Comment 3 John W. Linville 2012-04-18 10:22:31 EDT
It looks like iwlwifi is mismanaging its list of rx_bufs -- hitting the second WARN below, FWIW...

void __list_add(struct list_head *new,
                              struct list_head *prev,
                              struct list_head *next)
{
        WARN(next->prev != prev,
                "list_add corruption. next->prev should be "
                "prev (%p), but was %p. (next=%p).\n",
                prev, next->prev, next);
        WARN(prev->next != next,
                "list_add corruption. prev->next should be "
                "next (%p), but was %p. (prev=%p).\n",
                next, prev->next, prev);
        next->prev = new;
        new->next = next;
        new->prev = prev;
        prev->next = new;
}
