6 years ago I can confirm all of the above. There appear to be multiple problems that we did not have with Rocko:
1) With Sumo Yocto changed to incorporating bzImage into edison-image-edison.hddimg instead of vmlinuz. This is not a big issue as we only need to change the file name in meta-intel-edison-bsp/recipes-bsp/u-boot/files/edison.env.
2) It looks like we need to put the baud rate in the console (and earlyprintk) option to see any error messages with linux 4.16. Without this fix, when there are no errors, linux will still boot but very quietly.
3) With bzImage the kernel crashes as mmcblk0p8 does not appear. Adding rootwait to the kernel arg it waits forever. A usb disk does appear if present, sdhc not. As the mmc driver is built as module we need the initramfs to boot from emmc same as for sdhc. However Yocto builds bzImage-edison.bin into edison-image-edison.hddimg instead of bzImage-initramfs-edison.bin. @alext-mkrs do you know how to change which kernel image to build into the hddimage?
I could test the above because my mmcblk0p9 still contains bootable kernels so I can still boot from USB. mmcblk0p7 is a 9MB fs in a 33MB partition, too small to hold the initramfs kernel (12MB). I created a new fat32 partition in p7, copied bzImage-initramfs-edison.bin there and renamed to bzImage. Now it boots normally.

After building
masterbranch and flash the image, it stuck in a bootloop.Here is the boot information:
