Macbook Pro crashed

All of a sudden, my new Macbook Pro started to crash quite often, sometimes one crash every minute, and then crash around 15 minutes. I started my "fix" using different ideas.

First, I tried to recall what kind of changes I had before the crash happens, and consider "dropbox bug when its 2G storage limit is reached", so I quit the app, delete the app, and reboot system. However, crash still happens after few hours.

Second, after some search on google, some people suggest to delete system caches. I had a try to delete most system caches from various cache folders

~/Library/Caches
/Library/Caches
/System/Library/Caches
/private/var/root/Library/Caches
However, this clean up didn't save the crash.

Third, I looked the System Diagnostic Reports from Console application, and found most crashes with below information. It shows that it is Mac OS X system error.

After reading some discussions on apple support site, I tried to disable "Automatic graphics switching" from Apple -> System Preferences -> Energy Saver. After I disable the option for both batter/adapter, so far so good. I am not sure if this configuration change can solve crash issue.

Last, Mountain Lion is released today, so I can upgrade Lion to see if the crash goes aways with latest Mac OS. There are a lot of cool features in Mountain Lion, but I do hope the crash issue is resolved as well.
