Subject: ath9k bugs

hi,

I see occasionally bugs with ath9k hardware.

ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x00006040
ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up
ath: phy0: Failed to stop TX DMA, queues=0x001!

kernel: 3.6.11-5.fc17.x86_64

device:
ieee80211 phy0: Atheros AR9280 Rev:2 mem=0xffffc900116c0000, irq=19
05:00.0 Network controller [0280]: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01)


I also see the same bug with openwrt ATTITUDE ADJUSTMENT (12.09-rc1, r34185)
on a Buffalo WZR-HP-G300NH device:
https://dev.openwrt.org/ticket/9654

and "Rate marked as an HT rate but passed status->rate_idx is not an MCS index [0-76]: 77 (0x4d)"

-thanks-
