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: http://lxr.free-electrons.com/ident?a=microblaze;i=nox2apic

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.
