CI_DRM is indeed the build ID for Linux, but it is also used as an ID for the
type of run (post-merge testing of a kernel change, with the latest IGT that
was previously tested).

Fixed, for sure not: We do not update mesa nor piglit. Well, it could still be
an issue introduced by the kernel and then fixed immediately, but I doubt it
very much as developers usually don't look at mesa failures except during
pre-merge testing.

So yeah, it seems like it is a flaky test, with a very low reproduction rate...

I guess we have not updated yet these machines. I SSHed into it and it was
indeed using this old version of mesa (would be nice for piglit to store the
mesa version when using the gbm platform, it would save me time :D).

Thanks you for checking it out! The kernel's CI is very bug-centric, so every
failure needs to be documented in a bug, so as to provide a forum of discussion
about it and try to understand the possible impact of it (which depends a lot
on the reproduction rate). This is why you see from time to time bugs from me
:)
