LinuxQuestions.org - Having some problems mounting /dev/md0 device (it's mdadm stripping volume)

First I was getting errors and I couldn't even mount it after reboot... Then I must admit I've run fsck.ext4 /dev/md0 which seems that it changed something, now I can mount but I get this in dmesg.... Here's dmesg excerpt:
