--- Comment #58 from CheatCodesOfLife mesa@suchmail.net --- 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: http://blog.kember.net/articles/reisub-the-gentle-linux-restart/
