Look at /var/log/Xorg.0.log and dmesg, see the error message, then attach /sys/class/drm/card0/error.

/sys/class/drm/card0/error

The Xorg log says that it has detected hung GPU.

dmesg outpout:
[  222.804045] [drm] stuck on render ring
[  222.804053] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Any suggestion about what part for code that could make the GPU hungs are very helpful. I will work on it.

It seems that Firefox get frozen for few seconds when access google.com/chrome on Windows Vista, but later it will display the page, however Windows display an error message saying there is hardware issue in the video card.

PS: I have used Linux for more than 3 month on this laptop and I have not this issue before.

crash dump from /sys/class/drm/card0/error

I am having the same problem since the last system update. I'm also running 64 bit and I have the same graphics card, so it really seems to be the same issue.
I'm getting the error in chrome, when I'm opening the details view of an extension in the Chrome App Store. Gnome's Oops dialog screen thing will pop up, but the screen doesn't go black.

Below are packages from the last system upgrade that I think could be relevant.

I'll also attach the crash dump. If there is anything else that could be of help, please let me know.

Could you please explain what this bug is a "blocker" for?

I'm unable to navigate to website in FireFox or Chrome because this issue.
youtube and many others website that have some graphics make the screen black.
I was forced to drop linux because this issue and I went back to my MS Vista.
