I have also similar experience with my automated tests (automated
alarming does not work yet ;-)), I am still in the beginning.
I do there a ramdisk boot to create an overlay mount with the fresh
modules on top of an ordinary rootfs. initramfs mount is
ok, but the microsd card fails.

Testing from a ramdisk I get:
/ # ls -l /dev/mmcblk0p2 
brw-------    1 0        0         179,   2 Jan  1  1970 /dev/mmcblk0p2
/ # mount /dev/mmcblk0p2 /mnt/
[  682.819061] Filesystem requires source device
[  682.825103] Filesystem requires source device
[  682.830810] Filesystem requires source device
[  682.836303] Filesystem requires source device
[  682.843078] Filesystem requires source device
[  682.847991] Filesystem requires source device
[  682.853149] Filesystem requires source device
mount: mounting /dev/mmcblk0p2 on /mnt/ failed: No such file or directory

64GB microsd at omap_hsmmc correcly recognized. 
Last known successful boot: next-20180830

so you are not alone with such problems.
will investigate further

Regards,
Andreas
