Ok and isn't it a "bad" thing ? I mean, even if the video driver
crashes, I still want to have the ability to reboot the right way,
avoiding corrupted files and WIP lose.

Another thing is a non-critical module that can crash, but because not
used by all apps on the machine, letting them ones that can continue run.

But I don't know what is the approach of FreeBSD and devs about that.
