There is a problem with s2ram on 4.16, and it has now been propagated
to 4.15 and 4.14 stable updates.

It originates from

commit 62c00e6122a6b5aa7b1350023967a2d7a12b54c9
Author: William Grant <william.grant@canonical.com

    x86/mm: Fix overlap of i386 CPU_ENTRY_AREA with FIX_BTMAP

s2ram works OK on PAE kernels, breaks badly on non-PAE. I do not think
that the problem can be duplicated in VMPlayer, but it is 100%
reproducible on a "real" hardware.
System goes to sleep OK, but when woken - it reboots the PC.

The issue is tracked in Bugzilla bug 198763
[https://bugzilla.kernel.org/show_bug.cgi?id=198763]

Thanks, Woody

Thanks for digging into this so far. Can you please provide dmesg output
from a PAE=y and PAE=n kernel after boot?

Thanks,

Certainly. I understand you want dmesg output for kernels build with and 
without PAE, not just PAE=n on the cmdline :-)
Here it is...

Thanks, Woody

Thanks for providing the data. It did not pinpoint the issue but at least
it gave me the hint to look into the right direction.

Does the patch below fix the issue for you? It's untested as I'm at home
and have no access to a 32bit machine right now.

Thanks,

Subject: x86/cpu_entry_area: Sync cpu_entry_area to initial_page_table
From: Thomas Gleixner <tglx@linutronix.de>
Date: Wed, 28 Feb 2018 21:14:26 +0100

The separation of the cpu_entry_area from the fixmap missed the fact that
on 32bit non-PAE kernels the cpu_entry_area mapping might not be covered in
initial_page_table by the previous synchronizations.

This results in suspend/resume failures because 32bit utilizes initial page
table for resume. The absence of the cpu_entry_area mapping results in a
triple fault, aka. insta reboot.

Synchronize the initial page table after setting up the cpu entry
area. Instead of adding yet another copy of the same code, move it to a
function and invoke it from the various places.

It needs to be investigated if the existing calls in setup_arch() and
setup_per_cpu_areas() can be replaced by the later invocation from
setup_cpu_entry_areas(), but that's beyond the scope of this fix.

Thanks for the patch, good news, it did fix the problem.
I did 2 builds and both worked OK over the s2ram cycle.

It will be necessary to add the patch to 4.15-stable and 4.14-stable, I 
believe that both have now broken s2ram.

I will build tomorrow 4.15 and 4.14 with your patch and try it out - the 
patch seems to apply OK to 4.15.7 and 4.14.23...

Thanks, Woody

Right, it's already tagged for stable.

x86/cpu_entry_area: Sync cpu_entry_area to initial_page_table

The separation of the cpu_entry_area from the fixmap missed the fact that
on 32bit non-PAE kernels the cpu_entry_area mapping might not be covered in
initial_page_table by the previous synchronizations.

This results in suspend/resume failures because 32bit utilizes initial page
table for resume. The absence of the cpu_entry_area mapping results in a
triple fault, aka. insta reboot.

With PAE enabled this works by chance because the PGD entry which covers
the fixmap and other parts incindentally provides the cpu_entry_area
mapping as well.

Synchronize the initial page table after setting up the cpu entry
area. Instead of adding yet another copy of the same code, move it to a
function and invoke it from the various places.

It needs to be investigated if the existing calls in setup_arch() and
setup_per_cpu_areas() can be replaced by the later invocation from
setup_cpu_entry_areas(), but that's beyond the scope of this fix.
