Hi Adrià,

Are you getting this by trying to run MK8 in Cemu? Or some other way?

Could you try running through Andrey's instructions here:
https://bugs.freedesktop.org/show_bug.cgi?id=105251#c23

That didn't work on my system (log was truncated) so they've kinda stopped
looking into it, but if you could get them the complete log maybe they'll find
something?

I have the same thing where I can ssh back in, but can't fully `shutdown -h
now` as it hangs part of the way through.

You can reboot more gracefully by doing this:
