My Kernel bug is celebrating 2 years. Can you help me fix it?

[Peter Senna Tschudin]

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? 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?

Thank you,

Peter

P.S Yes, it works on Windows.
