Request to pull in an upstream bug fix for GPU Turbo for Intel Chipsets

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1146425

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

It doesn't look like commit 9104183dad6314c55344d65738cd719b909a3e0a applies cleanly to Precise or the upstream 3.2 kernel. Do you happen to know if work is being done upstream to have this commit backported?

Don't think there is some work happening to backport this for upstream. But we already have a backported patch for precise kernel. Patch is attached for your reference. This patch was created and tested on Ubuntu 3.2.0-37. It also applies cleanly on Ubuntu-3.2.0-39

commit 9104183dad6314c55344d65738cd719b909a3e0a is already in the Quantal and Raring kernel, so I'm marking this Fix Released for Quantl and Raring.

~/linux$ git describe --contains 9104183dad6314c55344d65738cd719b909a3e0a
v3.5-rc1~83^2~8^2~14

I'll then open up nomination for Precise and submit this for SRU there. Thanks.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
