I'm actually working on reworking that whole scheduler logic, and move
some of it into mac80211. Could you test this (WiP) patch and see if
that has the same problem?
It had some serious conflicts in ath10k, due to my local changes, so
I did not actually test this.
Can send you a version without the ath10k changes tomorrow if you'd like
to test - but will try to reproduce myself as well...

But, a revert of the atf patches (a6e56d749 and 63fefa050) appear to
have resolved the issue. I'll test more with these reverted, and maybe
will have time to work more on actually fixing upstream code next time
I move to a newer kernel (and/or after your pending changes get in).
Ah, that narrows it down some. Well, that is the code I'm hacking on
currently anyway, so let's see if we can't get it fixed as part of that
series :)
i have some addition information for you maybe. in the same timeframe i
noticed a increased memory usage for ath9k devices.
maybe that helps. so i hit memory boundaries on embedded devices with
dual interfaces and just 32 mb  ram now which wasnt the case before
is this patch worth to try from my side?
This is probably because of the added queue space. Which is sort of by
design. In 3ff23cd5654b9c8f4d567caa73439b4c39fbeaae we lowered the
default limit for non-VHT devices to 4MB. But if you have several PHYs
on a very memory constrained device you could still run out I guess.

`echo fq_memory_limit 2097152 > /sys/kernel/debug/ieee80211/phy0/aqm`
would limit it to 2MB for that phy...
what if i tried that already? :-)
Hmm, then it's maybe a bug? Changing the limit makes no difference at
all? Does your build include 0bfe649fbb133? What are values of the
maybe it makes a change but i run into oom after a while as well
counters in /sys/kernel/debug/ieee80211/phy0/aqm ?
i will check the current state in the next days. havent checked it over the last 2 months on the affected device
