Can you bisect? Also please attach your dmesg output.

Bisect didn't work. There is a regression between 4.17 and 4.18-rc4 on ext4fs that causes it fail to mount a file system:

set 11 08:16:49 coco.lan kernel: EXT4-fs (dm-13): ext4_check_descriptors: Block bitmap for group 0 overlaps block group descriptors set 11 08:16:49 coco.lan kernel: EXT4-fs (dm-13): group descriptors corrupted!
