Comment 78 for bug 1189850

I was able to reproduce that stack trace from Xorg log and intel driver is not an issue here at all.

I found out that the cause of this is the fast spinning mouse wheel. I have a mouse with a wheel which can be scrolled like in 'free roam' mode, without that 'clicks', you know. And if I scroll too fast that stack appears. As before dmesg is clean from any i915 errors and no error state was caught. So, that stack is not related to the bug at all.
