Default Bug#619022: linux-image-2.6.38-1-686: Screen corruption with i855

Package: linux-2.6
Version: 2.6.38-1
Severity: normal

See the attached image.
It is usually evident scrolling pages and with changing elements (like
Gnome system activities icons). The right part of any window title bar
is always corrupted.

I've already seen this problem with 2.6.38-rc6 from experimental, get
much better with rc7, then regressed with rc8 and the stable release.
Reading from upstream changelogs looks like it's a known problem that
they think it's solved but evidently not in my case.

The rc7 changelog report this:
-------------
commit c2e0eb167070a6e9dcb49c84c13c79a30d672431
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Tue Feb 22 18:25:49 2011 +0100

drm/i915: fix corruptions on i8xx due to relaxed fencing

It looks like gen2 has a peculiar interleaved 2-row inter-tile
layout. Probably inherited from i81x which had 2kb tiles (which
naturally fit an even-number-of-tile-rows scheme to fit onto 4kb
pages). There is no other mention of this in any docs (also not
in the Intel internal documention according to Chris Wilson).

Problem manifests itself in corruptions in the second half of the
last tile row (if the bo has an odd number of tiles). Which can
only happen with relaxed tiling (introduced in a00b10c360b35d6431a9).

So reject set_tiling calls that don't satisfy this constrain to
prevent broken userspace from causing havoc. While at it, also
check the size for newer chipsets.

It is likely the patch that reduced a lot the corruption for me.
But evidently this may have caused some trouble since rc8 and the
stable release changelogs reports this:

-------------
commit 0ee537abbd10a9abf11e1c22ee32a68e8c12ed4a
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Sun Mar 6 09:03:16 2011 +0000

Revert "drm/i915: fix corruptions on i8xx due to relaxed fencing"

This reverts commit c2e0eb167070a6e9dcb49c84c13c79a30d672431.

As it turns out, userspace already depends upon being able to enable
tiling on existing bo which it promises to be large enough for its
purposes i.e. it will not access beyond the end of the last full-tile
row.

Some days ago i've used rc8 for an entire day, despite the screen
corruption, but in the evening the system eventually freezed with a GPU
hung in the system log. Maybe not related.

Please report this upstream on <https://bugs.freedesktop.org>, under
product 'DRI', component 'DRM/Intel'. Let us know the bug URL so we can
track it.

Once a job is fouled up, anything done to improve it makes it worse.

bugs.freedesktop.org?
So do you think it's a bug in X.org and not the kernel?
But if i use 2.6.37, as now, the problem is not present. Shouldn't be
reported to bugzilla.kernel.org?
