How to debug Linux console freeze

I used Buildroot for the i.MX6UL EVK evaluation board, and that's working fine.  I'm using Buildroot for our i.MX6UL based product, and the kernel boots and I can login, but shortly after that the console hangs. 

I've tried the following:

* Set ulimits in a start-up script.

* Blink an LED.  The LED stops blinking at about the same time as the console hangs.

* Check available memory; looks fine.

* Check /var/log/messages; looks fine.

* Check dmesg; nothing suspicious.

I'm hoping for suggestions on how to debug further.
