There's nothing about the RX descriptors that I've seen that indicate what's going on. Sometimes I see a corrupted RX descriptor.

When it happens, check the output of 'sysctl dev.ath.X.txagg=1' (check dmesg) where X is the physical NIC. In your instance it should be 'dev.ath.0.txagg' for ath0. There are still some issues with TX buffer exhaustion and lockups, as well as some as of yet unknown hangs due to BAR TX handling. Adrian
