Do you run your NTP server at the 1000Mb level?
Anyone who is running a heavy traffic UDP server and is getting kernel panic crashes will come across this thread. They have every reason to have this info. This will help them and save them weeks of troubleshooting.
If you don't tune your NIC drivers for heavy traffic you'll run into kernel panics. See thread: https://forum.netgate.com/topic/144075/ryzen-3-2200g-randomly-crashing/22
And existing (Not as fine tuned) documentation: https://docs.netgate.com/pfsense/en/latest/hardware/tuning-and-troubleshooting-network-cards.html
This just adds on to that existing NIC tuning doc for handling heavier traffic loads.
