You are spot on, both are rather exotic test cases at least as = far as reports go; that is what intrigues me even more ;) >=20 > Equally, since AFAICT Brandon hasn't had a working AQM setup on this = box before. It could be useful if the Gentoo script works, to prove = that AQM + fq_codel can work correctly on Brandon's box. I guess since we just thought sqm-scripts to allow verbose = debugging output (into a log file) I thought it is time to advertise = that feature ;) >=20 > If the Gentoo script _wasn't_ working, that's when I'd suggest tearing = it down e.g. to eliminate fq_codel as an issue. Rather than specify = fifo explicitly, just don't run the fq_codel command (assuming that = actually does something sensible, which can be checked using `tc = qdisc`). >=20 >=20 > 2) More specifically, you didn't mention trying "simplest.qos". This = would i) simplify the setup we're trying to debug, and ii) it might show = if there's a bug with the more complex bandwidth calculations / = assignments in "simple.qos=E2=80=9D. Oh, you had mentioned that already and I fully agree that = getting a simple test cases going is going to help a lot.

Again, I fully agree, I guess I should have mentioned that I = have no genuinely new advice but rather just recommendations for slight = variations on the way. Sorry for muddying the water here.
