--- Comment #34 from Martin Sandsmark <sandsmark at samfundet.no> ---
I looked at the stuff Samuel found out and went to look at the libdrm git,
where I found a couple of commits related to passing buffer alignment
restrictions to the kernel, which I thought looked plausibly relevant to my
layman eyes.

So I installed libdrm-git yesterday, and I haven't had a crash in almost two
days. 

It's hard to definitely say if it is fixed because of the spurious nature of
the bug, but it looks good so far (if I'm not mistaken there could also be
several reasons for the miptree to not be allocated, though, so it's not given
that all crashes with this backtrace are related).
