So I'm putting this here in the hopes that someone might know an answer, but more importantly to document the issue for anyone else searching the web.
I use my machine in both OSX and Windows.
For gaming I boot into windows.
The card I have is a PCI-E card that has beefy power requirements. Both the PCI-E power supplies on the MB are used to power the card. In 10.6 this was no problem.
In 10.6.1 this was no problem.
10.6.2 and 10.6.3 will both cause the machine to KP during the boot up process, well before you can get into single user mode or safe mode.
As of now, I have confirmed that by unplugging the video card's power, the card appears to go into some kind of "safe mode" with the fan fully on, and the machine will boot just fine.
I'm going to try switching the video card slots to see if that makes a difference, but I think the Mac side has to have the primary video card in the first slot to work. Anyone else run into this before? Have any other suggestions?
