Well, the Intel GPU issue seems likely to cause problems for lots of people:

Although it looks possible that it mainly affects old chipsets (ie the
two reports are for a Bay Trail chip and a Core 2 Duo chip - I have no
idea how they compare).

That probably means there are a lot of machines out there, but likely
not the kind that most kernel developers will be testing, so not a ton
of reports until it hits distro kernels etc.

It looks like Maarten is already involved.
