Error log grabbed from my eeePC.

I saw this display bug after I upgraded to linux 4.3 on my archlinux.

Display is completely useless with my old eeePC using this chipset :

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)

But it works on my laptop which is using a "younger" Intel chipset :

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I reported this bug on archlinux bug tracker :

https://bugs.archlinux.org/task/46968

And here is the error log related to the bug I got on my eeePC.

I hope it is not a duplicate.

Looking at the beginning of error log, and google it to find this discussion.
