Hi @moeller0,
I don't remember having Fatal HW Error > 0, but I get lots of stuck beacons.

         MAC Hang: 46
     Stuck Beacon: 749162
Tx DMA stop error: 170
Rx DMA stop error: 3

Sometimes the interface hangs up silently (no dmesg output).
I might be wrong but I think this issues started around the time mac80211 intermediate software queues were introduced.
