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?idx7299
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.

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

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:

Let's add some folks who know about x2apic and VT-d. It's hard for
people to magically pick stuff out of the LKML firehose :)

Windows 7 doesn't use x2apic mode.
Windows 8 does and this same problem happened with this model: see
http://forums.toshiba.com/t5/Windows-8-8-1/Resume-from-standby-issue-on-R830-PT321A-01K002/td-p/330110
Seems like your model was recently added to Toshiba's Windows 8
compatibility list: http://support.toshiba-tie.co.jp/windows8/list_au.htm
Check for a more recent BIOS update that may fix this problem.

Thank you for the information. The model is similar to mine, probably
the same motherboard. My tests were with Windows 7.

I do that weekly since February last year, and there are no updates
available. The bad news is that the model was discontinued, so it is
possible that there will be no more BIOS updates. I'll write to
Toshiba Europe GmbH asking for a fix, by my hopes in getting an answer
are low.

And more importantly, probably the same system firmware.

Ok.

I would file it under ACPI; perhaps a simple means of determining this
system firmware does not reliably support x2apic can be found (or perhaps not).
Please read REPORTING-BUGS; the latest is here
