Thanks for investigating this issue. Yes, t is possible that the difference in behaviour that we see could be related to the fact we use different bootloaders. In order to make things easier, I am sharing a Buildroot image for imx51-babbage that contains U-Boot 2018.05 + kernel 4.17.2: https://www.dropbox.com/s/yevnu4y1zdchnbt/sdcard.img?dl=0 Please flash it directly to the SD card via dd and boot it. You will notice that it will boot normally. Then please copy a 4.18-rc1 zImage into the first SD card partition and you will notice the hang.
