I bought a batch of three Udoo Bolt V8s and one of them has very crippling hardware issues. In general it works correctly, with normal performance. However, some of the PCI-e devices are not available. From what I can see, Ethernet and NVME. They are completely gone in every OS I have tried, and behavior suggests even from firmware. There are no related errors in OS boot up logs. Additionally the power LED behaves strangely. When connected to power it's completely off, and when started it use the amber LED. The Arduino LED flashes normally. The other two works correctly, with devices present and green LED when running. Would you from this description be able to determine what kind of problem this is, eg. power delivery to a section of the board? And if so, could it be solve by a simple replacement of a component?
