Hey doksmf,
Were you able to figure out what was going on?? I’m running into the same issue running into the same issue. Please see the relevant section of the kernel log.

I’m running a TX2 with 3 USB3 cameras on a hub. I have some heavy usage on the CPUs but haven’t maxed out the cores.
Although one thing that I have observed is that it usually doesn’t crash if I’m interacting with the system . I’m not sure if its relevant. Initially I suspected a thermal issue, thought it was happening due to over heating or something, but then I ventilated it a couple of fans (TX2 sits in an enclosure), But this still occurs from time to time…
I have another TX2 that I run the same setup on, but i haven’t encountered this problem on that … May be I have a faulty unit?
Any insight would be helpful…
Thanks
