MacBookPro3,1 will not suspend.

Release Information:
Description: Ubuntu natty (development branch)
Release: 11.04 alpha2

While performing the 11.04 Laptop testing: snr-001 (suspend/resume smoke test), I have found the MacBookPro3,1 will not suspend properly. I am able to consistently reproduce this problem by selecting the session icon -> suspend menu.

The laptop will act like it is suspending the the power will shut down the screen will go black, the drives turn off everything appears to work as expected. However, it won't stay powered off. Once it shuts down, it automatically powers itself right back on. I can then log in again and everything is right where I left off. I can repeat this process over and over again with the exact same results.

I have performed the : ubuntu-bug -p linux

I have attached suspend and resume messages from the kernel.log.
