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, and older.
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:
