I have reported a bug more than two years ago and it is still
affecting me. The bug report gives some information:

https://bugzilla.redhat.com/show_bug.cgi?id=787299

I have tried basic debug instructions from:
https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt

And everything works as expected when:
# echo freeze > /sys/power/state
# echo disk > /sys/power/state

I have asked for help for fixing it:
https://lkml.org/lkml/2013/11/1/186

But I don't have a serial port. How can I debug this issue without a
"real" serial port? Or what else can I try?

You need to create a kernel with networksupport,
setup "netconsole" you need a second computer to receive the issues.

I have tried, and it does not work. The kernel do not start running
properly after resume, so there is no network...

How can I explore the hint
about the problem only happening with VT-d enabled in BIOS? How can I
explore the hint about the problem not happening if the option
nox2apic is passed to the Kernel?

never heard about that until now, obviously there is a bug in several
acpi's that can be triggered. If your systems works with nox2apic
as bootparameter you should be happy since a workaround is available.
Information about it is used can be find here:

Sorry, I'm not happy with the workaround, I want it to work. Thank you for
the link, I'll check it.

Thank you,

P.S Yes, it works on Windows.
