Hi, Rafael and other people.

First some context:

I did a good amount of tests.

Yes, I did do tests with /sys/power/pm_test. The results (in an
ascii-art table) that I got with kernel 2.6.31-rc5 were:

test with /s/p/pm_test |  result
-----------------------+------------------------
core                   | comes back from "sleep"
processors             | comes back from "sleep"
devices                | comes back from "sleep"
"none"                 | hangs in the real test

I'm writing this from memory, but I can repeat the tests, of course. It
would be nice if other reporters also did the same, so that we can
isolate the problem here.

Or, if they already did the tests, it would be nice if they could
summarize the tests.

I also tried to use /sys/power/pm_trace, but without much success.  I
don't remember any hash or matches line, but I can, of course, try it
again.

Oh, just so that you get an idea of what happens with my computer (and I
would love it if the other reporters confirmed what they are seeing),
here is what happens when I press the sleep button under any kernel that
I tried:

,----
| * the machine goes to sleep, staying with the light on the power button
|   blinking;
| 
| * if I press the button again, the notebook gives all symptoms of
|   resuming;
| 
| * just when you think that it will wake up, it turns itself off;
| 
| * after 1 or 2 seconds, when you think that it is powered off, it
|   turns itself on again (yes, "out of the blue");
| 
| * after that, it hangs with a black screen and no responses, no
|   feedback, no network activity (I tried to ssh into it), no pings, no
|   Magic SysRq, no nothing.
`----

Under Windows Vista (that came preinstalled), I do:

,----
| * press the power/sleep button;
| * the machine goes to sleep;
| * press the power/sleep button again;
| * the machine comes from sleep.
`----

I have already tried to:

* enable and disable Kernel Modesetting (it's an ICH8-based chipset);
* booted with a full system;
* booted with init=/bin/bash (so, no acpid taking over /proc/acpi/event);
* upgrade and downgrade the BIOS version;
* used kernels from 2.6.24 to 2.6.31-rc8.

I also tried ykzhao's suggestion of

  "echo mem > /sys/power/state; dmesg > dmesg_after; sync;"

but, as I naively would expect, there's no time for a dmesg to be
written to the disk, apparently.

Oh, I read some of the other bug reports and it seems that the other
posters also have a realtek 8169-driven ethernet card (can you confirm,
people?).

I tried "ifconfig eth0 down"'ing and even removing the module before
putting it to sleep, but no success either.

Well, as you can see, there's something highly magical that Windows
seems to be doing here that Linux can't (up to now).

As always, I am open to any suggestions and can perform any tests that
you want me to (and I can reconduct anything that was done already).


Thanks, Rogério Brito.

Replied in the Bugzilla, sorry for failing to notice you sent it as e-mail.

Hi, people.

First of all, to the bug reporters: please, let's get a bit more closer
and try to join our forces.

Triaging the bug report, seeing what still happens with the current
kernels etc. would all be helpful if we want to get our notebooks
working.

OK, now to the problem itself.

After some time without internet connection (humpf), I am back online
and I just did a git pull and a new kernel is being baked, soon to be
served. :-)

I did collect quite a bunch of extra information (including newer blobs
of dsdt, after the firmware upgrade from the firmware from MSI) and I
will upload those in a moment.

I hope that this will help us to better decide what is the culprit and
how we can better address this problem (perhaps asking MSI for some
involvement?).

Anyway, just as an extra piece of information, my notebook is what MSI
calls an MSI Aesthetic PR200 (well, at least after flashing it, that's
what it reports :) and it didn't die with this upgrade).

Some extra pointers (a script, actually) of what I did to create a boot
USB "disk" are outlined here: http://rb.doesntexist.org/diary/2009.xhtml


Hope this helps so far, Rogério Brito.

Thanks for being persistent.

Can you please attach the output of dmesg from 2.6.32-rc5 and the output
of lspci from the system to the bug entry?
