Hello.

I have problems resuming from suspend on my machine with a XFX GeForce 9300
motherboard using any kernel later than 2.6.36.

I've done a git bisect and this is the final result:

   drm/nv50: import initial clock get/set routines + hook up pm engine

   This will make nouveau_pm attempt to report the card's current performance
   level both during bootup, and through sysfs.

   This is a very initial implementation, and can be improved a *lot*

The problem is 100% repeatable and goes like this:

- Boot any kernel later than 2.6.36, while testing I boot the kernel's recovery
mode option.
- Suspend machine, while testing I run pm-suspend.
- Attempt resume.
- The machine sort of wakes, but the screen is still in power save mode and the
keyboard doesn't light up. After roughly 30 seconds, the machine reboots.
- Nothing in the logs after reboot.

I am currently running Debian Wheezy, but I've had the same problem with Debian
Squeeze (with backported kernel 2.6.38.2) and Fedora 15.

Resume works as expected with kernel 2.6.36.4 and older. If I run a working
kernel and add "nomodeset" to the kernel command line, the machine behaves
similarly to when the problem occurs, with the difference that it doesn't
reboot after 30 secs, I have to reset it manually.

At the moment I'm running 2.6.35.14, which is the latest currently maintained
kernel that doesn't have any issues on my machine. Hopefully this won't be the
last usable kernel on the machine, the hardware isn't very old.

I'd be happy to supply any information needed, I've attached lspci output and
the git bisect log to start with. Please note that the last 4-5 good bisects
actually had other issues, during boot the screen goes blank when modesetting
kicks in, I had to log on blindly and run "pm-suspend". After successful
suspend/resume, the screen starts working, both on the console and in X.

Cheers,
Daniel

Can you comment out nouveau_pm_init / nouveau_pm_fini calls from
drivers/gpu/drm/nouveau/nouveau_state.c on e.g. 3.0 kernel and see if it fixes
resume?

And please attach dmesg output.

Tried it on 3.0.4, no difference. Attached dmesg, but be aware that I can't get
any info from the computer after a failed resume until it has been rebooted.

Ok. So this commit is unlikely to be the culprit.
2 another ideas:
- does suspend/resume works at all without nouveau?
- can netconsole catch anything after failed resume?

Blacklisted nouveau with 3.0.4, the screen is still black after resume but the
machine is alive and I can ssh into it. No reboot.

Netconsole didn't produce anything after resume. Verified that it worked by
inserting a USB stick before resume, but nothing logged after. No ping
responses either, the network's probably gone.

Starting netconsole however changed the behaviour a bit, the machine reboots a
little faster, about 20 seconds after I hit the power button to resume. Without
netconsole it takes 40 seconds until it reboots.

I finally managed to get some output and there is a kernel panic, see attached
netconsole.log.

1) If without nouveau you cannot resume properly, then your problems with
nouveau are not nouveau fault. Maybe you could fiddle with some BIOS options
and see how it will affect s/r.

2) Machine Check Exceptions report *hardware errors* - your hardware is
probably dying.

I have no idea why it started with kernel upgrade.

I've done that in the past, when the problems started with kernel 2.6.37.
Couldn't find anything that improved the situation.

1) Resume/suspend with any kernel older than 2.6.37 works without a hitch, no
MCE.
2) Besides resume problems, the machine is rock solid with both older and newer
kernels.
3) When nouveau is blacklisted, there is no MCE. The machine wakes but doesn't
activate the monitor correctly, I can however ssh into the machine.
4) I have no problems with resume/suspend when running Windows 7 on the machine
and no crashes either.

Semms unlikely to me that if the hardware truly is faulty the only situation it
ever shows up is when nouveau is loaded during a resume from suspend with a
kernel newer than 2.6.36.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
