Comment 14 for bug 1678184

I'm also experiencing issues since ugprading to 17.04. When I switch to another TTY (via ctrl-alt-f1) the following errors get printed to the screen:

I also tried to run `smartctl -t long /dev/nvme0n1p7` however the results seem to indicate that the tool doesn't work with my particular SSD:

I'm using a Dell XPS 15 9550. Is there anything I can do to help you guys debug the issue?
