As I said, this seems like a regression in 2.6.36 from 2.6.35 (which
is why I emailed after 2 months :) ). You mentioned earlier in the
thread that you were going to submit the patch to head, if there is a
separate bug/thread tracking that, I can send followups to that.

I believe I have the right patch:

*** 225,234 ****
  	int error = 0, i;
  	u32 size;

!
! 	common->rx_bufsize = roundup(IEEE80211_MAX_MPDU_LEN +
! 				     ah->caps.rx_status_len,
! 				     min(common->cachelsz, (u16)64));

  	ath9k_hw_set_rx_bufsize(ah, common->rx_bufsize -
  				    ah->caps.rx_status_len);
--- 225,234 ----
  	int error = 0, i;
  	u32 size;

! 	size = roundup(IEEE80211_MAX_MPDU_LEN + ah->caps.rx_status_len,
!                        min(common->cachelsz, (u16)64));
!         common->rx_bufsize = min_t(u32, size,
!                                    SKB_MAX_ORDER(NET_SKB_PAD +
common->cachelsz, 0));

  	ath9k_hw_set_rx_bufsize(ah, common->rx_bufsize -
  				    ah->caps.rx_status_len);
