What is the md5sum for the firmware file /lib/firmware/rtlwifi/rtl8712u.bin? 
Over the weekend, there was a report of another device that had problems with 
firmware that was added to the linux-firmware repo in July with md5sum of 
c6f3b7b880aefb7b3f249428d659bdbb. An older version with md5sum of 
200fd952db3cc9259b1fd05e3e51966f works in that case. I'll send you this one 

I have a Netgear WNDR3300 and also get the addbareq events, but I do not get 
freezes. I'm not sure the message is correlated.
