I am using an i.MX6ULL on a custom product with the Linux vendor release. BSP I am testing with is based on " rel_imx_4.1.15_2.1.0_ga ". Once the system reaches the Linux log in prompt and systemd-networkd.service is disabled the board will lock up after roughly 10 seconds.
If I log in, enable systemd-networkd.service, and reboot before the system locks up everything will work fine.
If the service is enabled by default I use the following commands to test with.
systemctl disable systemd-networkd.service
I also tested the above commands on Linux mainline release " v4.12.4 " and it does not have this issue.
