This bug was about suspend to RAM. That has been confirmed as working in
comment #31.
Please file a separate bug for the hibernate issue.

Most of the time suspend to RAM works for me with Intrepid but randomly
the keyboard and touchpad will not work.
The network and X come back to life and the power button works but
keyboard and touchpad do not. Only resolve is to hard power off.

Linux charding-laptop 2.6.27-9-generic #1
Did not quite work for me in Intrepid Alpha 5 with all the updates. The
result is the same as in previous two Ubuntu releases. The system does
not wake up from suspend to ram on it's own. (Unless I don't hold down a
(any) key on the keyboard. Then it wakes up in ~10-15 seconds).

Seems to be working for me in Intrepid alpha 5 too using live CD.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

This problem (keyboard failure after resume) is still present for me in Hardy
but appears to be fixed in Intrepid alpha 4 (for me with the live CD, at least).
In Hardy, my suggested fix above also doesn't work because the suspend/resume

Suspend to RAM does not work well on HP notebook nx7400 in
Feisty Beta almost works - it manages to wake up from suspend2ram just
fine, only the display stays off, as others have noted. It can be fixed,
though (at least it works for my nx7400 flavor).
There were 2 steps to enable display to resume:
1) I compiled i8042 as module, configured /etc/default/ac

Hello,
The brightness problem occurs even if the driver is compiled as a
module. Any keyboard or mouse activity doesn't turn it back on. Only the
brightness keys do. So, I'm guessing that that brightness problem is
related to some weird power management feature.
I wouldn't mind the brightness pro
When you compiled the kernel yourself with i8042 as a module, did the
brightness issue still occur? What I am wondering is whether the
brightness is down because of a power management setting, but never
comes back up because there is no event from keyboard or mouse to tell
it to turn back on. If yo
Hello,
About the screen. It doesn't seem to be turned off. I can see everything
that happens as the laptop resumes. It's just that the brightness is
turned all the way down (lower than possible by using the brightness
keys). I can even see the messages as I shut it down by pressing the
power butto
Same for me. It seems clear that i8042 as a module is the solution and
unloading/reloading this and psmouse on suspend/resume is necessary. This
clearly needs changing in the releases though.
The question now I believe is whether the screen is turned off and you have to
press the brightness butt
Hello
I have exactly the same problems as Andrei Moldovan. I have not tried
to recompile the kernel myself as yet.

Hello,
The new kernel (2.6.20-12) is still compiled with the i8042 driver
built-in. Resume works, but the keyboard is inactive. Same problem as
before.
I've tried compiling the kernel myself with the driver as a module and
suspend/resume works, but I've had trouble compiling the restricted
module
Some fixed went into -11/-12 for this laptop. See if they help.

Hello,
As stated in the duplicate bug, the problem is the i8042 keyboard driver
that is built into the kernel. If the driver is compiled as a module and
removed before suspend along with the psmouse module, suspend works.
The problem that appears now is that the screen is turned off and you
