Latest MacBook Pros suffering from GPU-related freezes - Canadian TV, Computing and Home Theatre Forums

Numerous owners of the latest 15" and 17" MacBook Pro models have taken to Apple's support forums to report an issue that causes their systems to freeze, with one user going so far as to successfully reproduce the problem on every floor model at a local Apple Store.

User ND381 narrowed down the problem to using discrete AMD Radeon GPUs—his tests repeatedly showed the issue would occur when CPU intensive operations coincided with running apps that cause Mac OS X's automatic graphics switching to move from Sandy Bridge's integrated Intel graphics to the discrete GPU. User Chullo then performed similar tests on all the 15" and 17" MacBook Pros on display at his local Apple Store. "[T]hey all failed—much to the surprise of the genius helping me," he wrote.

Apparently that was patched in yesterday's release of OS X 10.6.7

I don't own one, so I cannot confirm, but I just throw that out there in case anyone is suffering.
