I think you need to use the unstable compat-wireless snapshots; I have a feeling that the above doesn't have all of the tx queues. Check out ath5k.h, the txq array in struct ath5k_softc should have NUM_TX_QUEUES entries, an earlier version only had 2. Although your compiler generates rather different code from mine (different config or whatever), it looks like the oops happened in the list_for_each_entry(... txq->q ...) -- but I don't see how that can happen in my copy, since txq[i].q is initialized at the same time as txq[i].setup. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
