I modified patch a little as:

And it did triggered WARN once at morning, and didn't hit KASAN. I
will
run for a while more, to see if it is ok, and then if stable, will try
to enable SFQ again.
Excellent news !
We will post an official fix today, thanks a lot for this detective
work
Denys.
I am not sure it is finally fixed, maybe we need test more?
I'm doing extensive tests today with identical configuration (i had to
run fifo, because customer cannot afford anymore outages). I've dded sfq
now different way, and identical config i will run after 3 hours approx.
