Barebox and ext4 ? problems

Hi,
i just noticed that Barebox 2017.08.0 has trouble with one of my ext4
partitions. My i.mX6q device has both SD-Card and eMMC. Normally I boot
from SD-Card, and then from there I use normal "fdisk" / "mkfs.ext4 -F
-j -L $label /dev/$dev" to create the ext4 partitions. Then I mount this
and rsync the contents of the SD-Card into the eMMC partition.
Now, when I boot into Barebox, I can't access the /boot device. Look at
the weird flags:
barebox:/ detect mmc3
barebox:/ mkdir /mnt
barebox:/ mount /dev/mmc3.0 /mnt/
barebox:/ ll /mnt
drwxrwxrwx 0 .
drwxrwxrwx 0 ..
?--------- 0 bin
?--------- 0 boot
?--------- 0 dev
drwxr-xr-x 4096 etc
lrwxrwxrwx 9 home -> /opt/home
drwxr-xr-x 4096 lib
drwx------ 16384 lost+found
drwxr-xr-x 4096 media
?--------- 0 mnt
?--------- 0 opt
?--------- 0 proc
drwxr-xr-x 4096 root
drwxr-xr-x 4096 run
drwxr-xr-x 4096 sbin
?--------- 0 srv
?--------- 0 sys
?--------- 0 tmp
drwxr-xr-x 4096 usr
drwxr-xr-x 4096 var
So, some directories like "boot" aren't directories. Moreover, some
directories that I can access have the wrong contents:
barebox:/ ll /mnt/media/media
drwxr-xr-x 4096 .
drwxrwxrwx 0 ..
crw-r----- 0 console
lrwxrwxrwx 11 core -> /proc/kcore
lrwxrwxrwx 14 fd -> /proc/self/fd/
crw-rw-rw- 0 full
crw-r----- 0 kmem
brw-r----- 0 loop0
brw-r----- 0 loop1
brw-r----- 0 loop2
brw-r----- 0 loop3
brw-r----- 0 loop4
brw-r----- 0 loop5
brw-r----- 0 loop6
brw-r----- 0 loop7
...
/media should however be empty, not contain files from /dev !!!
The SD-Card however is correct:
barebox:/ umount /mnt
barebox:/ detect mmc1
barebox:/ mount /dev/mmc1.0 /mnt/
barebox:/ ll /mnt/
drwxrwxrwx 0 .
drwxrwxrwx 0 ..
drwxr-xr-x 4096 bin
drwxr-xr-x 1024 boot
drwxr-xr-x 1024 dev
drwxr-xr-x 5120 etc
lrwxrwxrwx 9 home -> /opt/home
drwxr-xr-x 1024 lib
drwxr-xr-x 1024 media
drwxr-xr-x 1024 mnt
drwxr-xr-x 1024 opt
drwxr-xr-x 1024 proc
drwx------ 1024 root
drwxr-xr-x 1024 run
drwxr-xr-x 3072 sbin
drwxr-xr-x 1024 srv
drwxr-xr-x 1024 sys
drwxrwxrwt 1024 tmp
drwxr-xr-x 1024 usr
drwxr-xr-x 1024 var
(also the /media there is empty). Similarly, when I mount the eMMC from
Linux, I also get the correct files:
root at my:~# mount /dev/mmcblk0p1 /mnt/
root at my:~# ll /mnt/
total 84

Questions:
* Did Linux 4.9.x or e2fsprogs 1.42.12-2+b1 from Debian Stretch use some
partition flags / format that Barebox 2017.08.0 doesn't support?
* any ideas on how to debug this further?
Greetings,
Holger
