Description of problem:
I suspend the system to RAM using the Fn+F4 key. When waking the system up, the desktop is shown for a second, but then the system immediately suspends to RAM again. I always have to wake the system up three times until it is finally up again.

When I have suspended to RAM using the Gnome "turn off" dialog, the system wakes up correctly though.

It is a Lenovo ThinkPad R61 with Intel graphics.

Version-Release number of selected component (if applicable):
Fedora 10 x86_64 with all updates applied.
Kernel 2.6.27.21-170.2.56.fc10.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Suspend to RAM using Fn+F4.
2. Wake up using the power button.
3. Wake up two more times to finally get the system working again.
  
Actual results:
When waking up, the desktop is shown for a second, and then the system suspends to RAM again.

Expected results:
System just wakes up.

Additional info:
With an earlier ThinkPad R61 model, Intel graphics, F10 x86_64 and all updates applied, the Fn+F4 suspend is working fine. I have no idea why the affected system should behave differently, but it does.

There is no obvious hint in dmesg why the system immediately goes to sleep again.
