hey, pls try l *(ath9k_tx_start+0x284), yesterday i did the same in
the latest wireless testing tree it pointed to line 1929 of xmit.c

sc->tx.seq_no +=0x10;

also did few suspend/resume in my machine, nothing interesting happened

before receiving the email to do the above code with gdb I had cleaned the
tree out with git clean -fx so rebuilding might have misalighned things(but
could be wrong)..

seems gdb is not working with that code but works if I remove _start.
(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;
392			ar9003_paprd_populate_single_table(ah, caldata, chain);
393		}
395		ar9003_paprd_enable(ah, true);
396		ath9k_ps_restore(sc);
397	}
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.
