Comment 28 for bug 990129

After booting the 3.4 kernel on my macbook pro 2,2, my computer would either freeze on the first suspend attempt or if the first suspend worked subsequent suspend attempts would always work until reboot.

More Info:

Since my initial post my computer (with the 3.4 kernel) would freeze on suspend when I would do network related changes. ie) configuring a new router / moving to a different network. Freezing would happen on the first suspend attempt after rebooting. To be able to suspend (without freezing) after doing network releated changes, running update manager and performing updates seemed to fix the problem. Changing the network again would result in similar behavior.

Today I just updated to 12.10. Not sure if suspend works better on the 3.5 kernel.

# uname -a
Linux john 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Hope this info helps.
