The bug has been diagnosed and fixed upstream, there is no need to provide additional info (all info you may need is in the bug report).

[Joseph Salisbury (jsalisbury)]

An SRU to Raring will be needed if the commit that hits Linus' tree is not Cc'd to stable.

[Joseph Salisbury (jsalisbury)]

The upstream fix can be tested with the following kernel:

Subject: drm/i915: Fix up sdvo hpd pins for i965g/gm

From: Daniel Vetter <email address hidden>

commit 4f7fd7095d85cd31c86cb9ba87bc301319630ccc upstream.

Bspec seems to be full of lies, at least it disagress with reality:
Two systems corrobated that SDVO hpd bits are the same as on gen3.

v2: Update comment a bit.

This fix is upstream as of v3.11-rc2:

git describe --contains 4f7fd70
v3.11-rc2~17^2~2^2~35

Can you test the latest Saucy kernel and confirm this bug is fixed, since it has been rebased to upstream 3.11? If Saucy is fixed, please change the status for Saucy to "Fix Released".

Raring will receive this fix through the normal stable update process, since it was cc'd to stable.
