Description freebsd 2012-09-13 09:50:02 UTC

	When doing large transfers the ath driver runs into
	"issues".
	When running with SCHED_ULE and PREEMPTION I see messages
	like: 
messages.4.bz2:Sep  2 17:04:29 cakebox kernel: ath0: stuck beacon; resetting (bmiss count 4)

	This can even cause the AP to go into a state where it becomes impossible to associate. I then need to stop dhcpd, hostapd, ifconfig wlan0 down and start everything back up.
	
	If I include the diagnose/debug options I still saw these messages
	in my last test:

Fix: Switching to SCHED_4BSD without PREEMPTION helps but I still see
	stuck beacons.
	Attached a transcript where I run a few diagnose tools
	while I initiated and run a transfer.

Comment 2 freebsd 2012-09-19 19:54:16 UTC

When doing large bulk transfers I'm now seeing a lot of these in my  
dmesg buffer:

ath0: ath_tx_aggr_comp_aggr: AR5416 bug: hasba=0; txok=1, isaggr=1,  
seq_st=1339
ath0: ath_tx_aggr_comp_aggr: AR5416 bug: hasba=0; txok=1, isaggr=1,  
seq_st=1510
ath0: ath_tx_aggr_comp_aggr: AR5416 bug: hasba=0; txok=1, isaggr=1,  
seq_st=1726

Attached my kernelconf and a recent dmesg output (just a lot more of  
the above).

batch change:

For bugs that match the following
-  Status Is In progress 
AND
- Untouched since 2018-01-01.
AND
- Affects Base System OR Documentation

DO:

Reset to open status.


Note:
I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
