Hi,

have the same laptop model (8919DFG with NVidia). I did not have any
problems with suspend to RAM with 2.6.28-11.38-generic, but suspend to
disk did not wake up properly. I only got up to a very distorted (256
color palette???) image of my desktop, and then the laptop froze.

Today I upgraded to 2.6.28-11.39 and installed the checkbox package as
well. Then I ran the tests for suspend, which all passed, but they are
S3 suspend only anyway. But then I suspended to disk again via the KDE
menu and then restarted after a couple of minutes. Got the same
distorted frozen desktop as before, but this time it blanked itself
after about 15 seconds, then reposted itself,.... was frozen for a bit
again,... and finally appeared normally. After that the wlan and
bluetooth devices reconnected themselves without any problems.

Sorry to say but this is one of the unfortunate combinations of NVidia
GPUs and motherboard/chipsets, that have problem with restarting the X
server without rebooting the kernel, because they go into a lock for 30
seconds in the kernel. I always need  to tweak my [k|g}dm configs to
increase the X server timeout to 40 seconds minimum in order to be able
to logout and login again. I think it might be the same problem at the
root of this two seemingly unrelated issues.

For comparison I attached what was left in my dmesg buffer after so many
suspends/wake-ups. You can see some of the last suspend-to-RAM tests
from the checkbox script (going into ACPI S3 state/recovering from S3)
and then the last one is S4, suspend to disk. And I'm happy to say it
woke up even from an encrypted swap.

Hope you will experience a better result when you test the last kernel
package. I'll keep testing every new kernel packages until official
release and hope not to see any regression.

Kind regards

Todor
