        Oh, as if you knew that I had a number of:
                ath: phy1: Failed to stop TX DMA, queues=
        lines in dmesg, quick testing did not allow me to get those with 3.10.11-2, but I will need to test further...

        So I tested tc_stab and htb_private from the AQM tab, both work equally well.

        I think so, at least it works :)

        Have a great trip.

oh, this guilts me!  ;)

        Thanks a lot.

        RRUL-Testing against Toke's server shows great results, local rrul testing between osx 10.8.4 machine on sw10 to a net server running on an linux x86_64 3.10.1 machine on se00 is quite bad though (I assume I now run into the wifi issues on the macbook or the router as this is the first time I test against a machine with considerable larger bandwidth than the wlan). The rrul plots still are quite interesting, as I could nicely see anticoorelation between up and down bandwidth (shared medium)

No, its possible we have a new problem...
 

If I get round to it I would like to re-enable fq_codel on all interfaces (now it is just running at ge00/ifb0) to see whether this can ameliorate the issue at least a bit.

Note, I enabled the log for /usr/sbin/deblaot (by editing/etc/hotplug.d/iface/00-debloat) and got the following:
root@nacktmulle:~# cat /tmp/debloat.log
fq_codel_ll
fq_codel_ll
fq_codel_ll
fq_codel_ll
root@nacktmulle:~# cat /tmp/debloat2.log

No. This behavior is new.

I used to be able to

contents of /tmp/wtf:

qdisc change dev sw10 parent 1:1 handle 10 fq_codel limit 500 quantum 1000
qdisc change dev sw10 parent 1:2 handle 20 fq_codel limit 1000 quantum 1000
qdisc change dev sw10 parent 1:3 handle 30 fq_codel limit 1000 quantum 1000
qdisc change dev sw10 parent 1:4 handle 40 fq_codel limit 1000 quantum 1000

and then
cat /tmp/wtf | tc

Usage: tc [ OPTIONS ] OBJECT { COMMAND | help }
       tc [-force] -batch filename
where  OBJECT := { qdisc | class | filter | action | monitor }
       OPTIONS := { -s[tatistics] | -d[etails] | -r[aw] | -p[retty] | -b[atch] [filename] }

Which is how the debloat script historically did everything. Now the only syntax that works is:

root@cerowrt:/etc/hotplug.d/iface# tc -b /tmp/wtf

I think this is a regression in tc

Not sure whether that is new, as I never enabled the logs before. I guess I will see what causes these… (I assume an improper set of arguments to tc). And now I am trying to ind my way around debloat, but lua is totally new to me...


Best Regards & many thanks
