acpidump output

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.

dmesg from 2.6.38-rc2

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

new acpidump output with bios version a10

I found a new BIOS version and did a update, but wakeup got not changed.

new dmesg from 2.6.38-rc2 with bios version a10

I found this in dmesg (with both bios versions)

From the attached dmesg it looks like you don't use a KMS graphics driver.

What graphics adapter is there in your machine?

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).

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.

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.
