Bug description:
Hello,
In 16.04 lts (Ubuntu 4.4.0-134.160-generic 4.4.140) with all
partitions in ext4 with flag meta_bg :
kernel: [ 1905.799557] EXT4-fs (dm-7): ext4_check_descriptors: Block bitmap
for group 0 overlaps block group descriptors
kernel: [ 1905.799858] EXT4-fs (dm-7): group descriptors corrupted!
Go back with the kernel 4.4.0-133-generic and all partitions mount
correctly.
It looks like this:
