Comment 241 for bug 760131

Oussama - This bug is about a power consumption regression between Maverick and Natty. If you are using Lucid (10.04.x) then you have a different bug.

The patch/es described in comments 236-239 will be available in the upstream kernel 3.3. Canonical has back-ported this patch into the forthcoming Ubuntu 12.04 "Precise Pangolin"'s 3.2-based kernel. Ubuntu 12.04 alpha 2 was just released today.
