new since this patch was applied, pings were stable before.

near max. I have a 12/1 line, and the spikes begin when I for example open
a twitch.tv stream, which has about 3mbit. I have checked this with bmon
too.

and behind it, from a pc for example which is connected to the 3800's
switch.

to another OpenWRT router (wbmr-hp-g300h), so double nated.

the problem line. But the CPU of the router never reaches anything
critical. For example I use IPSet DHCP rules to route twitch traffic
though my wan device, because all other traffic is going through an
OpenVPN tunnel.
I'm the one who posted regarding the latency, QoS, PPPoE, tx ring sizes
and latency (the one who replied to nbd a lot).
I'm not seeing the issue with twitch, but connections seem to be
establishing slower than before. It feels like some of the snappiness has
disappeared. Everything seemed to load instantly before the patch.
