Got a brand new 27'' iMac, installed Lion. The machine freezes randomly when starting to play videos, either on Youtube, Quicktime, iTunes.


When it freezes, the mouse still works, but the machine doesn't respond to any command, requiring me to hit the power button and restart the computer.


Searched on kernel.log and system.log, and found no crash/error/message.


Anyone suffering from the same problem? The machine is pretty solid, been running some OpenCL kernels too and they are ok. It's only video decoding (possible on the GPU) that seems to freeze randomly.

iMac, Mac OS X (10.7)
