Here is the release announcement:

https://lists.freedesktop.org/archives/mesa-announce/2018-February/000403.html

According to the announcement, the regressions were introduced in the
development of 17.3, so we've already had the bugs for a while.

Since updating mesa now would cause a lot of new rebuilds, I think we
should wait.  However, we could graft it if we get reports about GPU
lockups, or maybe even pre-emptively.  WDYT?
