As of r250406, I get a kernel panic whenever I bring wlan0 up because the assertion in if_ath.c:4317 gets triggered. I have reverted r250391 for now, removed sys/contrib/sys/dev/ath now that sys/contrib/dev/ath is in place and commented out the "ath0: ath_edma_recv_proc_queue: handled npkts 0" messages that Joshua also mentioned. Everything seems to be working fine (ie. connecting to my crappy WPA2 router).
