Comment 13 for bug 642518

Rolling back to the following packages resolves the issue for me:

linux-headers-2.6.32-23
linux-headers-2.6.32-23-generic
linux-image-2.6.32-23-generic

Since 2.6.32-23 works and 2.6.32-24 does not. Is this a regression introduce by Linux 2.6.32-24 rather than the drivers?

I have done some tests with the results below:

ATI 10.9 + 2.6.32-24 = Error
ATI 10.9 + 2.6.32-23 = No issue
ATI 10.5 + 2.6.32-24 = Error
ATI 10.5 + 2.6.32-23 = No issue
8.723-1 + 2.6.23-24 = Error
8.723-1 + 2.6.23-23 = No issue
