I think this is. It's interesting though that it is deauthenticating -- is there anything in the log before? But since you bisected it to the TX sync commit, I'd say let's try the below patch. You might have to adjust the iwl-mac80211.c file to iwl-agn.c, I'm not entirely sure what version has the moved code. Please let me know -- this commit is probably the right thing to do until we get rid of tx_sync completely.
