I have updated the USB cabling to introduce this USB isolator here:
http://www.analog.com/en/interface/digital-isolators/adum4160/products/EVAL-ADUM4160/eb.html
and that haws significantly reduced to occurance of the issue, but it just
happened again!
I have been redirecting the concole output using netconsole to another
machine and logged this:
