Resuming from hibernation on T61 with nvidia

Resuming from hibernation on T61 with nvidia

[dienet]

Hello

As far I can remember (since I have my ThinkPad T61), there is problem  
with resuming from hibernation (suspend-to-disk) on this system. And I  
know that there are lots of people with the same problem.
I was checking lots of kernel versions but with no luck.

Was is the problem? In my T61 I have 01:00.0 VGA compatible controller:  
nVidia Corporation G84M [Quadro NVS 140M] (rev a1) and I am using nvidia  
drivers (also checked quite a few versions without any luck). Suspending  
to disk is working without any problem. The problem is when I want to  
resume. The resume process is stopping at some point (I think after the  
pages are red) for about 60 seconds. After that time, the resume process  
is continuing, and after few sec, I am back in X11.

I have motivation to fix it, but:

1. How to trace it?
2. Is it possible to fix this? Maybe the fix should take place in nvidia  
driver (nvidia.o), and that can not be done. But maybe the fix can be done  
in kernel?

I want to notice that, if the fix will only work for me, then that is fine  
with me.

I know that answer to 2. might be hard, so maybe some guide how to trace  
the problem?

Hi,

[Adding linux-pm and linux-kernel mailing lists to CC.]

You can try using the pm_test framework for debugging this, to a certain
extent. See Documentation/power/basic-pm-debugging.txt for details on how
to use it.

Also, if you could post any logs that indicate the problem, that would
be great!

Thanks,

Does the same thing happen if you use nouveau rather than the nvidia 
drivers?

I will look into that.

At this point "the logs" are camera shoots of my monitor. I really do not  
know if there is some think else that can be useful.

Can not answer that, but this is not happening when using nv X11 driver.

In that case it's almost certainly something you need to bring up with 
nvidia.

Yes, but that might be hard, or even impossible. Maybe there is something  
that I can change in kernel to fix it, without breaking too much or not  
breaking anything ;)

Don't forget that you can use nvidia-reportbug.sh...can't remember
exactly what its called but
I know that nvidia does actually look at those generated bug reports.

OK ;) Got the motivation, I did send them the report, will see...

But I am still gonna check linux kernel trace methods, to know more.

So I run some test:

Using platform in state file:

1. echo freezer > pm_test - no problems.
2. echo devices > pm_test - problems: no picture (LCD is up and shining,  
but there is only black picture [even after 60 seconds]). I can use power  
button to shut down the system. Other keyboard keys are not working (I was  
trying to type reboot with no luck).
3. echo processors > pm_test - the same as above
4. echo core > pm_test - the same as above
5. I turn off the X11 (telinit 2), but the nvidia module is still loaded -  
no problems.
6. I left X11 working on f7 (7th tty) and switch to f1 (1st tty) - echo  
core > pm_test works OK, but switching back to X11 (alt+f7) will give me  
the same as in 2. I can change the brightness of black screen, but I can  
not go back to tty1 (ctrl+alt+f1).

Is there more I can do?
