Bug#690198: linux-image-3.2.0-4-686-pae: Screen corruption and flickering on acer aspire s5
Package: src:linux
Version: 3.2.30-1
Severity: normal
Dear Maintainer,
the upgrade from linux-image-3.2.0-3-686-pae to linux-image-3.2.0-4-686-pae
introduced screen corruption. Once the i915.ko drm module is loaded the text
console begins to flicker, once X/gdm starts the colors are corrupted and not
the entire display is shown. Suspend/resume is fixing this configuration.
I bisected a different kernel branch and found a commit, it has been backported
to the v3.2 stable branch as 8147cc255b1ab84cdb0d4b28cccf7fe59103dcee. Reverting
the change is fixing the corruption.

Can you test the fix suggested by Daniel Vetter upstream? I'm attaching
a backported version for 3.2, which you can apply to the Debian package
as described in
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>.
Ben.
