I'm having the same problem on a Samsung NC10 netbook. 945GM family as well. Works perfectly fine in 4.2.4. 4.3.0 creates the problem. The card crashes and you can interact with the desktop fully, but you can only see updates in the non-corrupted portion. VTs are also corrupted in the same way. You can still interact, but you can't see anything. I've attached my log as well.
Created attachment 119613 [details] intel driver crash on 945GM with 4.3.0
I should also note that I tested on my distro's vanilla kernel repo and had the same problem. Also, I'm using the 32-bit kernel since that is what the architecture is limited to.
still present in 4.4-rc2
Seems like this might be a dup of bug 92655.
I don't think it's a duplicate, because I tried the patch (https://bugs.freedesktop.org/attachment.cgi?id=119541) from #92655 and it didn't fix the errors for me. I don't have corruption though, just the errors. But I haven't used X extensively on 4.4-rc3 and gone back to an older kernel after seeing the errors in dmesg.
I am also seeing display corruption, on an Acer Aspire 3680, running 32b, where lspci gives: 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) On a 1280x800 display, the top two and bottom two lines appear normal. In the corrupted area, successive scan lines are displaced from the correct position, from the left to about 4/5 of the width, followed by normal text displaced vertically. This is still present in linux 4.3.3. In the 4.3.0 kernel, Xorg would still produce a normal display, but not with 4.3.3, except that the mouse cursor is displayed properly.

In Arch Linux, going from the Testing repository's linux 4.3.3-1 to 4.3.3-2, this problem seems to be gone.
