Aheros AR9565: buffer error messages from ath_edma_rxbuf_alloc and ath_edma_rxfifo_alloc

Hi,
I am the (happy?) owner of an Atheros AR9565 which used to work just 
fine.

I recently updated an old -current, and a flood of these messages bumped 
up:
Nov 13 17:47:16 test kernel: ath0: ath_edma_rxbuf_alloc: nothing on 
rxbuf?!
Nov 13 17:47:16 test kernel: ath0: ath_edma_rxfifo_alloc: Q1: alloc 
failed: i=24, nb
ufs=128?

Is there anything I can help with to improve this? Thank you.
