OK I see nothing odd with these values, and I do not see how
these values can make ath_rxbuf_alloc() barf. I'd like to
reproduce this myself at least once, I left iperf running over
night with no rants from SLAB. I should note this should be
reproducible with RX only if it is ath_rxbuf_alloc() to blame
but without a concrete reproducible instructions it is hard
to guess what to do and if this can only come up during RX.

Can you describe a little more when you have seen this? What
were you doing exactly, for how long? When was the last time
you saw this, what were you doing then?
