I have a dell Xps 15 9550 and I have installed Ubuntu Gnome 15.10 in the UEFI dual boot along with Windows 10. Ubuntu works fine but after running for a while it goes to the black terminal screen with these errors:

Image for error

I tried doing fsck but I am not able to unmount /dev/nvme0n1p8 as it says that the device is busy

It has SSD and the partitioning is:

The file systems containing Ubuntu seems to be damaged. Please start from a Live DVD/USB, open a terminal (Alt+F2) and run:

sudo e2fsck -p /dev/nvme0n1p7
sudo e2fsck -p /dev/nvme0n1p8

This either fixes the issue or uncovers more underlying issues.
