Bug 309935 – Xserver crashes with [drm:i915_gem_object_bind_to_gtt] *ERROR* Invalid object alignment requested 4096

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Justin Lecher (RETIRED) 2010-03-17 11:52:43 UTC]

Today randomly my X started to crash. The only things I know, that it happens when switching from one window to another. It happens at least when switching to ff and urxvt, but I think it is the switching not the app where it goes to.

dmesg says:

[drm:i915_gem_object_bind_to_gtt] *ERROR* Invalid object alignment requested 4096

Xorg.0.log says:

Backtrace:

Please try with a newer kernel. 2.6.33 should do.

Thanks

[Comment 3 andrex 2010-04-20 05:07:43 UTC]

I had exactly the same problem -- at least one X crash each day with the same error message usually after switching windows. Upgrading from sys-kernel/gentoo-sources-2.6.31-gentoo-r6 to sys-kernel/gentoo-sources-2.6.33 fixed the problem. I have not seen an X crash since the upgrade a couple of weeks ago.

(x11-drivers/xf86-video-intel-2.11.0)

[Comment 4 Justin Lecher (RETIRED) 2010-04-20 06:08:37 UTC]

Oh yes, that fixed it for me too.

Alright, thanks for the follow up.

Closing with the proper resolution.
