Kernel panic during first boot

I downloaded image of Ubuntu Mate 16.04 for RP2/RP3, installed it on sd card with dd.
After i adjusted config file for proper video mode and power on RP3.
I can see correct picture on HDMI output but kernel panic during kernel
boot. It says that can not mount rootfs on unknown block device.
Seems it is bug.
I did not dig deeply, just for information.

I will answer to my self :slight_smile:
during dd on 8Gb card as usual all cards have different amount of blocks. So my sd card was little bit smaller and ext4 file system was corrupted so:

2053 e2fsck -f /dev/sdb2
2055 resize2fs /dev/sdb2
2056 fsck.ext4 -f /dev/sdb2

it fixed problem
