Hi guys. I’m using NAVIO+ on Raspberry Pi2 and a Logitech C920. We have had problems with corrupted USB video that we didnt know the reason until we stumbled upon this post where we found other users with the same video corruption problem. In the post it was suggested that the FIQ drivers corrected the problem, and indeed it worked. The problem is that now NAVIO cannot stay online much more than a few seconds, hard crashing.
I took a look at /var/log/syslog and found that the stack trace went trhough scheduling code paths, which seems to indicate it is a RT kernel problem.
This problem is a showstopper for our application. Do you have any suggestions to enable FIQ or to stop the video corruption?
Can you confirm if this particular problem is also present in RPi 1 B+ setup?
