It's not crashing, a filesystem has shut down....

Any I/O errors in the logs? i.e. is it a SATA issue and XFS is
shutting down to protect itself?

Well, that explains why you can't log in - your root filesystem has
shutdown. You need to separate your root filesystem from the data
filesystem so that when the data filesystem has a problem it doesn't
take the entire machine down (as you are currently experiencing).

If there are no I/O errors being reported before the filesystem shuts down,
can you provide more information of the type of I/O the system is executing
when the shutdown occurs?
Cheers,
Dave.
