My root ext4 gets mounted as ext2

[Shelnutt2]

I'm on a fresh funtoo install ontop of a fakeraid 0 array. I've build my kernel from source and included my filesystem drivers and I used genkernel to build by initrd (so dmraid can load). Everything is working fine except my root is mounted wrong. Here are two lines I see in dmesg:

[    0.223341] EXT4-fs: Unable to register as ext3 (-16)

[    8.603928] EXT3-fs (dm-4): error: couldn't mount because of unsupported optional features (240)
[    8.622661] EXT4-fs (dm-4): mounted filesystem with ordered data mode

It mounts everything else fine including my /home which is ext4.

# /etc/fstab: static file system information.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.

# See the manpage fstab(5) for more information.

what about this:
https://bugzilla.kernel.org/show_bug.cgi?id=12354

you may need to pass the 'rootfstype=ext4' kernel boot parameter with grub to get it to work.

You know, I remember MRD just went through something similar, I don't know why I didn't add in the kernel parameter. I'll see if that fixed it in a minute.


edit:
I'm still having the same issue. I'm going to move to btrfs soon here though.
