Impacted also in 16.04 lts (kernel 4.4.0-134-generic ) with all partitions in ext4 with flag meta_bg :

ext4_check_descriptors: block bitmap for group 0 overlaps block group descriptors

the flag meta_bg activates automatically by warming up a partition above 60GB (with lvextend and resize2fs).

go back with the kernel 4.4.0-133-generic and all partitions mount correctly.
