Just some extra information here: while I can hibernate with vanilla
2.6.28-rc3, upon resuming, it takes *minutes* (I don't know how many
minutes, but probably something like 5 minutes or so!) for the desktop to
have any effect (despite the fact that I can move the mouse without any
problems).

A new reboot is *much* faster than what I get with hibernate.

I can film that if desired.

This problem still persists.

A correction here: when I close the lid, the laptop suspends. I can try to
see if it hibernates.

Again, I am willing to get any debugging information or anything that is
asked me. I am testing things and I still don't have any production data on
that notebook.

BTW, I installed Windows Vista with a dual boot. I'm feeling tainted
now. :-(

Nice that the video proved useful to demonstrate the issue. I can take
another video to show the current behaviour with 2.6.28-rc3.

Right. Just for further information, this notebook here has a plain ICH8
chipset. The only thing that I think that is not from intel is the gigabit
ethernet, which is a Realtek one (it seems that the r8169 driver is loaded,
but I still have not tested wired connections).

Weird. I have a Dell Latitude D520 here (which I'm using for this e-mail)
and everything that I tried works fine (suspend, wifi, hibernation and even
the compiz stuff---which I promptly disable). It has a broadcom ethernet
that seems to use the b44 driver, but I have also not used the wired
connection here.

I'm streaming audio via daap to this notebook from a Kurobox (powerpc box)
with kernel 2.6.27 kernel (and my patches that were included in
2.6.28-rc3).

For me, nothing like this works. :-( I can open the lid and it still stays
sleeping. Pressing the suspend (poweron/poweroff?) button while suspended
only turns off the machine. :-(


Thanks again for any feedback, Rogério Brito.
