Apalis TK1: EXT4-fs (mmcblk0p2): couldn't mount as ext3 due to feature incompatibilities

I had to patch the kernel-source due to display voltages and frequencies (arch/arm/boot/dts: dts, dtsi,.). Unfortunately now I get a boot error which I cannot assign to my changes. Is there a menuconfig option that I should check for this:

sdargs=ip=off root=/dev/mmcblk1p2 rw rootfstype=ext4 rootwait
emmcargs=ip=off root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait

works fine!
