wr703n is AP mode. Version: AA 12.09 Revision: 36447. wifi stop work,
ssid not visible. This occasionally happen. I notice others meet same
problem,
ath79 driver have bug ?
1> run: iw wlan scan, have info
[ 2253.530000] ath: phy0: DMA failed to stop in 10 ms AR_CR=0xdeadbeef
AR_DIAG_SW=0xdeadbeef DMADBG_7=0xdeadbeef
[ 2253.540000] ath: phy0: Could not stop RX, we could be confusing the DMA
engine when we start RX up
[ 2253.800000] ath: phy0: Failed to stop TX DMA, queues=0x10f!
