If true, this sounds like some sort of erratum, so it would be good to
get some input from Intel, and I cc'd a few Intel folks.
It's interesting that all the systems below are from Asus. That makes
me think there's some BIOS or SMM connection, e.g., SMM traps the
register write and does something magic.
Does this problem happen after a full system suspend/resume, or does
it happen after runtime suspend of only the GPU? Or runtime suspend
of only the GPU and the upstream bridge?
Can we tell whether Windows rewrites this register unconditionally at
resume-time? If so, it may be more robust for Linux to do the same.
The whole thing is black magic, which I hate, but if it's our only
choice, it may be better to have this applied everywhere so we don't
keep stubbing our toes on new systems that require the quirk.

Can you attach the list below to a kernel.org bugzilla and include the
URL in your changelog?
