I discovered that my event counters were overstating the event counts (adding 
each enum's value instead of 1, D'oh!), but I'm still getting 
EVENT_CODE_SEQ_ERROR_IN_BURST events fairly often. I've modified the 
tx_waveforms.cpp example to count async events. You can get the source at 

It's showing about a rate of around 1.5 EVENT_CODE_SEQ_ERROR_IN_BURST events 
per 100 packets at 25 Msps. Is that rate expected? I think I can work around it 
for my current purposes , but I haven't done it yet.
