Comment 40 for bug 563156

The issue originally reported appears to be an ATI Graphics specific issue, likely triggered by the new KMS drivers being less sensitive to power consumption on the graphics side and the fans for the GPU are coming on. The other issues specifically those with Intel graphics or those related to upgrades are highly likley different issues. The complexity in separating issues of this nature makes it much more sensible to file an individual bug with all of your symptoms and system information in one place. This allows the triagers and developers to more readily examine the information and make a determination if your issue is one and the same as another and then duplicate the bugs if appropriate. We would rather have too many bugs than not enough.
