(maybe -next took this out or something) (gdb) l *(ath9k_tx_start+0x284) No symbol "ath9k_tx_start" in current context. (gdb) l *(ath9k_tx+0x284) 0x4854 is in ath_paprd_activate (drivers/net/wireless/ath/ath9k/main.c:395). 390 continue; 391 392 ar9003_paprd_populate_single_table(ah, caldata, chain); 393 } 394 395 ar9003_paprd_enable(ah, true); 396 ath9k_ps_restore(sc); 397 } 398 399 static bool ath_paprd_send_frame(struct ath_softc *sc, struct sk_buff *skb, int chain) right now I am running next, will wait for the RX DMA to get a clean trace, then will look to see.. as for the other issue I just rebooted and hit this during bootup.
