Pi hangs when nmea2000 connected
I have a pi5 with SSD and waveshare 2 channel isolated canhat, running a recent version of openplotter. Everything works great on my bench, connected to a garmin chartplotter and/or simulated data. I then sent it to a friend in New Zealand who installed it in his boat. Everything is good until he connects to his n2k network, then the cpu utilization shoots to 100% and the pi becomes unresponsive. Mouse stops working, doesn't respond to pings, no way to interact with it, but the display on hdmi is still okay. Power is provided by a U6223 buck converter that provides 6A, so I don't think it's a power problem. Maybe to much nmea data? Would filtering help? Any ideas on how to proceed or debug? Thanks!
