I have a XPS 15 (9550) running Ubuntu 17.10 that occasionally freezes with only the mouse cursor movable. I have to force reboot the system when it happens. When I try to switch tty these messages appears on the screen (https://pasteboard.co/GRJaXYe.jpg).
Previously I have a Windows partition on the same laptop that has the same symptom that has been fixed by using an alternate driver for the nvme ssd (Toshiba THNSN5512GPU7) as apparently this was a known issue for this laptop running on this type of ssd on Windows. I do not see any solution yet for linux so please help me out as I ran out of options other than swapping the ssd.
