How to resolve "Cannot mount ext4 filesystem" problem?

After last kernel update I have run into problems with starting system. My computer cannot start the system with new compiled kernel version. Only thing that I changed was root partition type. I've changed it from ext3 to ext4 filesystem. When I tried to run system with new kernel I receive this message:

mount: cannot remount block device /dev/sda2 read-write, is write-protected

Resolution

dmesg gives the answer, it says:

EXT4-fs (sda2): Filesystem with huge files cannot be mounted RDWR without CONFIG_LBDAF 

You need to compile your kernel with "Support for large (2TB+) block devices and files" enabled (CONFIG_LBDAF option in kernel config).
