So either the error message got silenced ;) or, = preferably, the root cause was fixed.=20 root@nacktmulle:~# cat /sys/kernel/debug/ieee80211/phy0/ath9k/reset Baseband Hang: 0 Baseband Watchdog: 0 Fatal HW Error: 0 TX HW error: 0 TX Path Hang: 0 PLL RX Hang: 0 MAC Hang: 259 Stuck Beacon: 1 MCI Reset: 0 root@nacktmulle:~# cat /sys/kernel/debug/ieee80211/phy1/ath9k/reset Baseband Hang: 0 Baseband Watchdog: 0 Fatal HW Error: 0 TX HW error: 0 TX Path Hang: 0 PLL RX Hang: 0 MAC Hang: 0 Stuck Beacon: 0 MCI Reset: 0 I fear this might be the logging=85 at least for ph0 the MAC hangs used = to correlate with the TX errors in dmesg...
