Comment (by tom3q):
I'm observing similar problem on TL-WR1043ND on OpenWrt Barrier Breaker
r42087. I'll try a newer build as well, but same was happening on last
stable Attitude Adjustment too. It happens quite rarely, though, but still
annoying. Nothing shows up in dmesg. My investigation showed up that
apparently RX still works, while TX is broken in this state.
