I am having the same error.


I got my 16" MacBook Pro a week ago and it worked fine for one day when it was connected to a charger. But if I close the lid and open it up in a couple of hours (I assume after the MacBook has gone from sleep to hibernation) it always does a cold boot. After I insert the password, I get a black screen and all the fans got 100% for one second. Then it boots again, I insert the password and I get logged in. I always get a crash report from the OS.


Back when I had 10.5.1 it was a kernel panic and said something about the CPU related setPowerState() function failing. I saved all these reports into files, but then one day the MacBook went into an endless boot loop and I had to reinstall the OS. That's when I lost 8 of these reports that I had stored on the disk.


Now with 10.5.2 I've only been getting GPU panic reports. Most of them have said "PowerPlay Failed Resume" and I was surprised that I found zero Google results with that exact text. Today I got my first "PowerPlay Failed to Initialize" and was able to find this forum thread with it.


I will be sending this unit back to Apple as I believe it to be a hardware issue. I've had problems with 10.5.1 and 10.5.2. I did a clean install of 10.5.2 and got the crash report even right after finishing the setup. I believe it's either in the CPU, GPU or the logic board.


I'll write here when I hear what they did to the MacBook in repairs.


P.S. During writing this post the MacBook did a sudden cold reboot while it was just on idle on the desk next to me. When I got to the desktop I got another "PowerPlay Failed Resume" but the system was also very unresponsive. I was unable to copy the full report to TextEdit or even press the "Send" button on the report. Mouse stopped moving. A minute later a black screen, 1 second of 100% fan noise and another cold reboot.
