I have a laptop running Arch Linux and found that upgrading from 3.5.6 to 3.6.2 had a huge impact on my battery life. Power consumption went from ~10W to ~20W. I initially thought it was a i915 driver problem since the CPU temps went up and so I opened this bug: https://bugzilla.kernel.org/show_bug.cgi?id=49031
However, as you can see if you read the bug's comments, after bisecting this I found the culprit to be commit 71a83bd727cc31c5fe960c3758cb396267ff710e: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=71a83bd727cc31c5fe960c3758cb396267ff710e -- Micael Dias -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
