[G45] blender-bin segv due to buggy intel driver

[Martin Olsson]

Binary package hint: blender

repro steps:
1. install mesa 7.6.0~git20090928.6829ef74-0ubuntu1~xup~1 from X-Updates PPA
2. launch blender
3. press the "render this window" button (it's the upper right most button in the lower half of the screen, look for the tooltip)
4. blender crashes and my intel driver spews nasty errors into dmesg

Note: nothing out of the ordinary happens when I do this with the current karmic mesa 7.6.0~git20090817.7c422387-0ubuntu6 installed.

no errors are printed to xorg.log but I include it for chipset info and whatnot

[Martin Olsson (mnemo)]

Even though this is _NOT_ a GPU freeze, I'm including the usual dri_debug.tgz dumps in case that's useful for some reason. X.org is very much usable after blender crashed despite the nasty errors in dmesg etc.

Here is my chipset, it's a desktop box (G45 chipset) with a GMA X4500HD intel card built-in:
