i.MX6Q Custom SBC: Lockup after "random: nonblocking pool is initialized"

PaulDeMetrotion · ‎12-08-2015

Working on a custom SBC base on the i.MX6Q. I am converting our BSP process from LTIB to YOCTO. I have created a custom device tree and built a core-image-base zImage. The boot proceeds quite far and then stops with no further console output. Any guidance would be appreciated. Here is the console output:
