[1.] One line summary of the problem:
intel_iommu=on under 4.13 breaks resume from suspend on my Thinkpad T560
[2.] Full description of the problem/report:
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=197029
With intel_iommu=on, on my Thinkpad T560 laptop, suspend does work,
but pressing on POWER / Enter / whatever key (which under 4.12 used
to resume the system) doesn't resume.
Instead, the machine doesn't do anything: system remains suspended,
the glowing LED keeps glowing, and my only option is to force a
hard shutdown with a long press on POWER, and start the system again.
Turning intel_iommu=off from GRUB, I am able to successfully resume
from suspend, like I used to be able to in 4.12.

[X. Other notes]
X.1. this is my first kernel bug report. I'm doing my best
to follow the guidelines, but may be imprecise or missing
debug info. Please ask if this is the case. Thanks.
I remain available for follow-up and testing.
X.2. This is a follow-up to downstream discussion:
- Arch bbs talk: https://bbs.archlinux.org/viewtopic.php?pid=1737688
- Arch bug: https://bugs.archlinux.org/task/55705
X.3. Over at the Arch bbs, someone suggested I try
`intel_iommu=igfx_off` rather than full `intel_iommu=off`.
It's not enough; even with `intel_iommu=igfx_off`,
resume is broken.
Same person on Arch bbs suggested my bug might be related to
https://bugs.freedesktop.org/show_bug.cgi?id=89360
X.4. Several reports of the same problem on Reddit:
https://www.reddit.com/r/archlinux/comments/72z2rv/linux_41331_is_in_core/dnmjaeo/
