Also here with r42616, Buffalo WZR-HP-G300NH2(Atheros AR7242 rev 1):
[97355.840000] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024
AR_DIAG_SW=0x42000020 DMADBG_7=0x000242c0
[97355.850000] ath: phy0: Could not stop RX, we could be confusing the DMA
engine when we start RX up
But I did not reboot the router, and it still is running.
I believe that the 2014-09-14 release, sorry I don't remember the cvs tag,
was running flawlessly.
-thanks-
