Subject: Baseband watchdog timer tripping on AR9342

On an AR9342-based AP, we see non-zero counts for
RESET_TYPE_BB_WATCHDOG and RESET_TYPE_BEACON_STUCK when trying to do
large uplink transfers from ~60 clients with some of them 30-40 ft
away.

All the other reset types have a count of zero.

These resets cause all the clients to disconnect.

Any ideas on how to avoid these resets and the subsequent disconnections?

Thanks,
- Harshal

I forgot to mention that there were three "Failed to stop TX DMA"
messages on the debug port which seem to map to the
RESET_TYPE_BB_WATCHDOG events.
