Mainboard: ASRock Z77 Extreme4 Graphics card: AMD Radeon HD6950 (r600/Cayman) Resuming from hibernation fails sometimes, but resuming from suspend never fails. Observable symptoms when it fails: After reading the complete page1? snapshot, the screen goes black, turns off (no signal) and the system hangs. No ssh or sysreq keys work, everything is frozen dead, leaving the reset button as the only option to get the system back into a working state. This is with the vanilla kernel, starting at least with 3.2-rc8 something, last version tested is 3.8.7. But in production, I'm using identical kernels with the tuxonice patches applied. Now one interesting feature of this is that it allows to retry a failed resume (reading the image again). And this - though it might sometimes need one or two tries - actually works! No filesystem corruption or any other problems. I've spent some time to narrow this down to some module, and it appeared that the issue doesn't happen with nomodeset=1. What's more relevating, is that it is not reproducible with a Radeon HD3650 (RV635 chipset) using the same module. According to the driver developers, for the driver there should be no difference between suspend/hibernate. Any idea what could go wrong here? Any chance getting to work hibernate/resume reliably on that machine with that graphics card? Unfortunately, this is really hard to debug. There seem to be no messages that would help in dmesg, netconsole is no help here, boot messages scroll over the screen extremely fast, too fast to read.
One additional note: The issue does not occur at certain cycles, sometimes three hibernation->resume cycles go well, then the fourth and fifth will not work, then the next four are ok and so on...
This seems a hardware unstable problem since you said the problem said unreproducible by using Radeon HD3650. Further more, this doesn't happen every time.
I would agree with you, but find some contradictions: 1) The system is otherwise *completely* stable, hibernate/resume being the only issue. 2) Hibernate/resume is no problem in Microsoft Windows 7. I know, these are different conditions, but still... 3) There are no problems on boot or with suspend/resume. Radeon HD3650 uses r600, but is different hardware, so not really comparable. If I could test another Radeon HD6950, then it would easier to say, but unfortunately, I do not have another test sample and won't be able to get one. Before simply declaring this an unstable hardware problem, are there no further methods to track down the issue? Isn't there a chance this could be a locking issue, or race condition, whatever?
Currently, have no idea. How about changing a higher power supply? or using a serial port to get debug info(the system maybe still survive).
I see. 750W should be plenty, and it's not bad quality. Besides, I don't think the graphics card draws that much power when booting. When playing 3d games, maybe. Perhaps I can look at that serial port stuff. I'll also try putting the graphics card in another machine, although I had an older p67 mainboard before where the same issue existed.
Ok. I think 750W is enough. Do you have some update about serial port debug?
ping ...
I wonder... Is netconsole that much different from serial console? I mean, will I get output right from the start, or only after reading the pageset1 (atomic copy)? Because if there aren't any differences, I won't get serial debug output either, right? I will need to find another computer with a serial port and a serial cable first. Unfortunately, I won't have access to the machine for the next two weeks, but I'll report back then.
While I haven't been able to get the equipment for serial console debugging, I think I have at least found a workaround: echo 0 > /sys/power/pm_async Since I've disabled async suspend/resume, the problem has not occurred anymore (16 attempts by now). The console reappears on each attempt, and there is a 3 seconds delay now before the computer starts reading pageset2. So it's indeed a software problem, not a hardware one. Now why does this issue happen only on hibernate/resume, but never on suspend/resume? I believe this is because of a BIOS setting (enabled by default) which forces to wait for all devices being ready before resuming from S3. The description for this setting _only_ talks about S3, not S4/S5. I have not tested this, so this may only be speculation, and the BIOS setting may not have anything to do with it, but I'd find it very probable. Setting pm_async to 0 is ok for me; I don't care if it takes 3-5 seconds longer, as long as it works. However, I guess it's still a bug and pm_async should work, so I'm going to try this serial console stuff anyway. Any recommendations from you concerning debugging steps now that I've narrowed this issue down?
I think you can try to find which device's async suspend cause this issue. I write a script which can run under /sys/devices to find which device's async is enabled. You also can run it under some specific device's sysfs node to narrow the scope or enhance the script to disable the async and test. #/bin/sh for i in `find . -name async`; do rlt=`cat $i` if [ "$rlt" = enabled ] ; then echo $i $rlt fi done
There are no async files below /sys/devices, and "*async*" doesn't reveal anything useful either.
Unfortunately it seems the problem is not solved completely. While it happens _much_ more rarely now (say maybe 3%), it still does even with pm_async deactivated. At first I thought it would be a different issue, but the symptoms are the same. While this makes reproducibility a bit harder, I know how to change that ;-) So I'll still have to get that serial console debugging stuff going.
Ok. This shows pm_async just alleviates the issue. Does the following patch work for you to find devices with async enabled. find /sys -name "async" | while read i ; do \ DEV="$i" ; ENAB="`cat $i`" ; \ if [ "$ENAB" = "enabled" ]; then \ echo enabled dev $DEV ; \ fi ; \ done
I've tried to get serial console debugging working today, but failed miserably because the USB<->RS232 converter refused to work as soon as I attached the null modem cable (device errors, not reconnecting on re-plugging with the cable). Maybe that null modem cable is faulty or too long and the cheap USB converter can't deal with it. I suspect that the cable is still good though and will see if I can find another old piece of hardware I can attach to the machine, without having to deal with that USB stuff. I've used that null modem cable ages ago... Next, I'm not sure I was correct about the problem not being solved completely. It could also be another driver problem sharing the same symptoms. It's a bit buggy with newer kernel versions, there are currently a few bugs open on freedesktop.org which might cause this. The machine hang two times while running, so it wouldn't be surprising if this was not related to suspend/resume at all. As for your script: Find did not find anything on my machine because I compiled the kernel without CONFIG_PM_ADVANCED_DEBUG enabled. I'll activate this, do some tests and see what they turn up.

Ok, the following statements deactivate async for the graphics card (+ its HDMI audio): echo disabled > "/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/power/async" echo disabled > "/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.1/power/async" This seems to have a similar effect as "echo 0 > /sys/power/pm_async". With this, I ran a series of 30 hibernate/resume cycles. The 7th and the 29th attempts failed (the last one failed twice), with the usual symptoms. So it seems that disabling async for the graphics card indeed only alleviates the problem. I will perform the same tests with pm_async deactivated just to be sure.
On the other hand, 0 of 30 hibernate/resume cycles failed with "echo 0 > /sys/power/pm_async". Maybe coincidence, but probably not. I will continue disabling async for additional single devices.
Thanks for test. I think you have done a very good job.

Disable pm_async is just to make all the driver suspend callback to be executed serially. So reassign this bug to Graphic category. > With this, I ran a series of 30 hibernate/resume cycles.

I believe I was wrong with this assumption. However, I got serial console debugging working now. Unfortunately, it does not reveal much, but here is the output anyway.

Any way to get more output?
If you install the userui binary in the initramfs, you'll be able to single step through the process and modify the TuxOnIce debugging settings as you go - perhaps this will help. Press 'P' to pause between steps, 0-9 to modify the level of debugging info that's displayed (9 = max info, including all kernel messages).
It took me a while because it turned out the old cable was faulty after all, and I had to replace it. Now that I got a new one, I installed an initramfs with tuxonice userui and tried to reproduce. Unfortunately, I was not very successful in getting more information. Here are the last lines of the log. Sometimes when it hangs, only the 20%....80% line gets printed and nothing more. Sometimes, it goes like this: ... TuxOnIce: Image found.^M^J Using dev_t 8:9, returned by blk_lookup_fs_info.^M^J Console is 67x240.^M^J Freezing user space processes ...

The lines are similar, but not always in that order. They also appear in dmesg when everything goes right, so they're nothing special. Any idea what else I could do?
This was a problem with the power management of the radeon graphics driver and should be fixed in 3.11, as long as one disables UVD with an unofficial radeon.no_uvd=1 patch. Since this is solved for me now, thanks for your help.
