Sleep failure code 0x00000000 0x1f006900
I have a new iMac 27" with OS X 10.7.3 with all patches and updates. Including the iMac Graphics FW Update 3.0. Since I updated my system (2 weeks ago), I have a serious problem of Sleep and Wake Up. Same problem during a fresh installation of Mac OS. 10.7.3 I was away of my computer during 20 min during the installation and when I came back, the system was sleeping. Impossible to wake up. I had to press the power button for 5-6 sec to restart the system.
Now I know the problem is not from an application or from my profile, because it wasn't create yet. I resetted the PRAM and the SMC, but still the problem of wake up. Here is my error code in the log.
There is someone that have got this error in the past?
Thanks
