Seem to be related to CAN transceivers... both seemed to be drawing too much current on 5V rail. This is the second time the CAN transceiver has been the culprit for a 5V rail drop.
Double check schematic connections and IC.

Looks like the schematic connection is wrong, connected VSS to 5V and VDD to GND. Should be the other way around.. This explains why whenever the CAN transceivers are soldered the 5V rail gets messed up. Need to rework the board by cutting some traces and jumping them to switch VSS and VDD.

Fixed in rev1, in vcu-hw repo commit 7288ddc6
