[ltp] Suspension to Memory / Disk using ACPI in T30

[Min-Ho Shin]

Hi,

I cannot get suspention-to-mem and to-disk working with my T30.
I tried both swsusp and suspend2.
I also used script which resolves T30 specific problem where the
backlight doesn't switch off (thinkwiki.org/wiki/How_to_configure_acpid.
I used above script and also hibernate scripts.
I also followed gentoo-suspend2 kernel and instructions, no luck.

Now I'm back to apm and I can only do suspend-to-memory.
I didn't try yet suspend2 with apm.

What happens is, when I issue suspend-to-memory, it suspends.
But, when I awake it up by pressing Fn-F4 or opening up lid,
it just reboots the system, not resuming.

When I issue suspend-to-disk, it just cannot go into sleep state and
wakes back up.

I disabled pcmcia cardbus service, all network devices and usb support.
No luck !

Anybody has the same experience ?

I use :
model = T30 2366-92U
dist = Gentoo
kernel = linux-2.4.12-gentoo-r10
                linux-2.4.13-suspend2-r4
                linux-2.4.14-gentoo-r4
              ( I tried all of them )

The following is what I see from /var/log/messages
when I try suspend-to-disk
