I've got a BeagleBone Black Rev C, with a canbus cape. It works great but occasionally the BeagleBone will freeze up during boot up and I've found that it's when the can modules are being loaded. I have been able to capture some information within /var/log/messages, but it's pretty much greek to me! Does anybody have any insight?
