I just uploaded a test patch to bugzilla.
Please have a look if that fixes the issue.

If not I would be interested in the output of your iTXQ status.
Enable CONFIG_MAC80211_DEBUGFS and run this command when the connection 
is bad and send/share/upload to bugzilla the resulting debug.out:

k=1; while [ $k -lt 10 ]; do \
cat /sys/kernel/debug/ieee80211/phy?/netdev:*/stations/*/aqm; \
k=$(($k+1)); done >> debug.out
