Hi,
As you have suggested I will try with kernel 2.6.14.5.This time
I tried something differenet.Now I changed my swap partition.Now my swap
partition is on LVM.So I reinstalled Linux-2.6.9 from cd. Then I
downloaded linux-2.6.13.3 and recompiled it.
I followed one document "acpi-how-to" and did the following steps to
suspend my system.

1. I did not use kernel parameter "resume= " in grub.config as it is
given that the 1st swap space will be used for image storage.

2.Then I create my initrd using the following command
mkinitrd --allow-missing -f /boot/initrd-2.6.13.3.img 2.6.13.3

3.Then I did the following
echo shutdown > /sys/power/disk
echo disk > /sys/power/state

It seems my system is suspended. So when I press the power button it did
not resume but restarted.In boot log message I found something like this
swapon:/dev/VolGroup00/LogVol01: invalid argument
rc.sysinit: enabling swap space failed

Now it seems my swap partition has been crashed.
So after rebooting I tried following command
swapon -s //showed nothing
cat /proc/swaps //showed nothing
free //this showed that the size of swap space is 0

So I tried to activate my swap space and typed this command
swapon -a

But this gave the following error
Unable to find swap-space signature
swapon:/dev/VolGroup00/LogVol01: invalid argument

Now I can not do any thing until my swap space becomes activated.
First I did not get why my swap space got crashed ??
Second is there any way to activate my swap space ??

Please suggest.

Thanks and regards,
Rasmit.

This only means swsusp tried to read a suspend image from the partition,
but it didn't found one (ie. normal).

Well, you're not giving a lot of information ...

Anyway, it's likely you're hitting a bug that has been fixed already.
Please try the 2.6.14.5 kernel and see if that works.
