We have a few nuc7i7bnh connected to USB 3.0 machine vision cameras with Ubuntu 18.04.
Some systems are randomly crashing. We don't if it's memory related or USB driver low-level related. Here is what we see in the logs:

Has anyone encountered this type of issue? If so, have you been able to resolve it?
Any help is greatly appreciated.
Hello alexandrebustamante: Thank you for joining the Intel® communities support.
As you can in the following link, Intel validated the NUC to work with Windows® 10 and all the drivers that we have available in our web site, belong to that operating system:
