When waking up from suspend to ram, computer falls to sleep again once, and then wakes up fine

[larsemil]

Binary package hint: acpi

When putting laptop to sleep using suspend to ram and later trying to wake it up, i get the password prompt from gnome and i can write, but seconds later it falls asleep again.
After waking it up a second time it wakes up fine and i can use the computer with no problems.

This i have on both my laptops!(Dell vostro 1220, and EEEpc 701)

Some not confirmed thoughts - I never got it when on AC - only on battery. And it does not happen every time but often enought to get disturbing.

After some more testing, we have found that it only occurs after falling to sleep on battery. If falling to sleep during AC power and then disconnecting the plug i dont get the behaviour of computer falling to sleep twice. Only when falling to sleep on battery.

I can absolutely confirm this bug. I'm using a Thinkpad T61. I can also confirm that this problem occurs only when on battery and not on AC.

Status changed to 'Confirmed' because the bug affects multiple users.

I have this problem on a Toshiba Satellite U305-2812 running 11.04 Natty i386. It happens when the laptop is on battery either suspending, waking up or both.
