Description Thomas Creutz 2011-01-29 20:37:48 UTC

since kernel >= 2.6.37-rc4 I cannot wake up my system from S3 standby.

my system is Ubuntu 10.04 with follow kernels from kernel-ppa.

2.6.32-28-generic-pae (
2.6.36-1-generic-pae (2.6.36)
2.6.37-8-generic-pae (2.6.37-rc4)
2.6.37-9-generic-pae (2.6.37-rc5)
2.6.37-12-generic-pae (2.6.37)

My System is: Dell Vostro 3700
For more details see attachment

So.. short explanation: after power on my laptop from standby it just stay black. when I press _short_ the powerbutton the system is powered off.

I also compared the kernel config from 2.6.37-8-generic-pae to 2.6.37-9-generic-pae - but there is no specified change to any acpi/power related stuff only some additional video- and dvb-drivers.

King Regards,

Can you verify that the problem is still present in the current Linus'
tree (2.6.38-rc2 at least)?

We've had several fixes in this area since 2.6.37.

dmesg from 2.6.37-rc4

yes, I will do it with the next reboot, mainline-kernel now installed from kernel-ppa

But also I want to add dmesg from working 2.6.37-rc4 with working resume/wakeup output.

yes, resume works, but not very well.. X needs really long to resume.. I attached the current dmesg

Comment 9 Rafael J. Wysocki 2011-01-29 23:53:02 UTC
From the attached dmesg it looks like you don't use a KMS graphics driver.

What graphics adapter is there in your machine?

Comment 11 Rafael J. Wysocki 2011-01-30 22:28:06 UTC
Well, I think the resume problem is related to the nvidia driver being used,
in which case I can't help you, because this driver is not supported by the
kernel developers.

You may get better results, as far as suspend-resume is concerned, if you use
the nouveau driver (still, I'm not the right person to ask for help with this
driver, because I don't use any machines with NVidia graphics).
Comment 12 Thomas Creutz 2011-01-31 20:42:00 UTC
ok.. I was expecting such a answer ;-)

but I prefer to use nvidia driver, because I need vdpau interface for hd video acceleration and good 3d support.

But I can blacklist the driver for a test... but I don't think that I need it..

in the last time/tries the wakeup works really good.. don't now what was wrong before.
Comment 13 Rafael J. Wysocki 2011-01-31 20:45:14 UTC
That's fine if it works for you.  There might be some transient error that
has been fixed in the meantime.

I'll close the bug as "unreproducible", please reopen (or file a new one) if
the problem continues.
