Aheros AR9565: buffer error messages from ath_edma_rxbuf_alloc and ath_edma_rxfifo_alloc

[José Pérez]

Dear Svatopluk,
tried again with current, and I get (almost) the same:
Nov 23 18:14:47 current kernel: ath0: ath_edma_rxbuf_alloc: nothing on 
rxbuf?!
Nov 23 18:14:47 current kernel: ath0: ath_edma_rxfifo_alloc: Q1: alloc 
failed: i=0, nbufs=128?
Nov 23 18:14:47 current kernel: ath0: ath_edma_rxbuf_alloc: nothing on 
rxbuf?!
Nov 23 18:14:47 current kernel: ath0: ath_edma_rxfifo_alloc: Q1: alloc 
failed: i=1, nbufs=128?

Ideas? Can I help?

Thank you.

Regards,
