Hello. I recently upgraded to FreeBSD 13.2-p1.  Since that time, perhaps 
a couple days ago my system has hung twice.   Prior to that on previous 
kernel versions, it had never hung.  There is no console output when it 
hangs it simply stops responding at the console and stops responding to 
network traffic.

The system specifics are below.  Is there anything I can do to help the 
kernel devs find the (presumably) new issue?
