I just subscribed to the list and looks like there are some followup patches not in my build so I'll have to re-test with the followups next. One question: Are these patches "Just Work" or do I need to do some tweaking of qdiscs, etc like the sqm or cake stuff needs? If so what are those? I did some testing this morning and I seem to have an additional problem than just the slowdown. When I run flent my against the ndb/stageing+patches the wifi on my laptop pukes after a few seconds and I have to disable/re-enable to get it back. Doesn't happen running the same test against a wdnr3800 running OpenWrt CC (my main AP). Here's a snipit of the kernel error. [301744.796063] iwlwifi 0000:3a:00.0: Microcode SW error detected.
