Hello guys I tried booting the following linux-qoriq-sdk after a bbappend was attacked to it and some configs were activated.
The problem was identified when enabling a number of configs for LTP testing:
CONFIG_TUN=y
CONFIG_KSM=y
CONFIG_NUMA=y
Maybe you could take a look and let me know of your solution.
I am investigating this in parallel but I believe your opinion on this is more advised than mine.

Setup the u-boot for NFS boot and launch the 'boot' command. The following output was obtained:
