>Description:
When BIOS SATA is set for AHCI mode chipset can see nearby networks but can't connect. When BIOS SATA setting is set to Compatibility then it works in a degraded mode from dhclient buffer issues to ath_edma errors, and 47% packet loss when ping is used. Here are some errors:
ath0: ath_edma_rxbuf_alloc: nothing on rxbuf?!
ath0: ath_edma_rxfifo_alloc: Q1: alloc failed: i=0, nbufs=128?
ath0: ath_edma_recv_proc_queue: Q1: NULL bf?
ath0: ath_edma_recv_tasklet: sc_inreset_cnt > 0; skipping
dhclient[1001]: send_packet: Invalid argument
dhclient[1001]: send_packet: No buffer space available
ath0: ath_edma_recv_tasklet: sc_inreset_cnt > 0; skipping
dhclient[1001]: send_packet: No buffer space available
dhclient[1001]: send_packet: Invalid argument
dhclient[1001]: send_packet: Network is down
