Hi. This is a follow-up of [BUG] 
https://bugzilla.kernel.org/show_bug.cgi?id=197029 ,
where Jarkko Sakkinen asks in comment 31 to move discussion here.

[1.] One line summary of the problem:

intel_iommu=on breaks resume from suspend on several Thinkpad models

[2.] Full description of the problem/report:

With intel_iommu=on, on several Thinkpad models (my personal T560, and
the X1 Yoga / Yoga 460 of commenters over at [BUG]), suspend does work,
but pressing POWER / Enter / whatever key fails to resume from suspend.

Instead, the machine doesn't do anything: system remains suspended,
the glowing LED keeps glowing, and the only option is to force a
hard shutdown with a long press on POWER, and start the system again.

[3.] Keywords (i.e., modules, networking, kernel):

suspend, resume, power management, laptop, lenovo, ibm, thinkpad, intel

[4.] Kernel information

[4.1.] Kernel version (from /proc/version):

Linux version 5.8.7-arch1-1 (linux@archlinux)
       (gcc (GCC) 10.2.0, GNU ld (GNU Binutils) 2.35) #1 SMP PREEMPT
       Sat, 05Sep 2020 12:31:32 +0000

This is the official `linux` package currently in Arch's `core` repo:
https://www.archlinux.org/packages/core/x86_64/linux/

[4.2.] Kernel .config file:

https://github.com/archlinux/svntogit-packages/blob/packages/linux/trunk/config

[5.] Most recent kernel version which did not have the bug:

Undetermined.

I witnessed the bug in Linux [ 4.13 , 5.8.7 ] but the bug predates 4.13.
I first noticed it in 4.13 because it's the first version where Arch
shipped a kernel enabling `intel_iommu=on` by default.

Since then, following the Arch Linux sister bug report linked below at
[ARCH-BUG], Arch kernel packagers switched back to `intel_iommu=off`.

[X. Other notes and bugzilla bug summary/chronology]

X.1. This is a follow-up to these threads:
      - [BUG] https://bugzilla.kernel.org/show_bug.cgi?id=197029
      - [ARCH-BBS] https://bbs.archlinux.org/viewtopic.php?pid=1737688
      - [ARCH-BUG] https://bugs.archlinux.org/task/55705

X.2. Over at [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 from suspend is broken.

X.3. The same commenter over at [ARCH-BBS] suggests this bug might be
      related to https://bugs.freedesktop.org/show_bug.cgi?id=89360

X.4. Problem was brought to the Linux IOMMU list:

https://lists.linuxfoundation.org/pipermail/iommu/2017-September/024382.html

X.5. Several Reddit commenters confirmed the problem:

      However, I couldn't find such an option in my T560's BIOS :-/

X.10. ... which was inconclusive to me, so to my followup, he replied
       at https://bugzilla.kernel.org/show_bug.cgi?id=197029#c23 with:

       > I have no idea about how this commit impacts the suspend/resume.
       > The fast way to make it work is to revert this commit,
       > or contact the commit author to rework it.

X.11. In the meantime, bugzilla commenter Albert attempted a revert,
       but was unsuccessful, as this patch no longer cleanly reverts.

X.12. On 2020-08-27, Alyssa Ross applied a patch functionally
       equivalent to reverting 422eac3f7deae34dbaffd08e03e27f37a5394a56 ,
       but this did not solve the problem for her, see
       https://bugzilla.kernel.org/show_bug.cgi?id=197029#c30

X.13. On 2020-08-28, Jarkko Sakkinen asked to bring the discussion to
       this mailing list, and here we are.
