Comment 195 for bug 760131

Just to add a counterpoint, I've found that things are more or less working well for me with the new kernel - it's definitely better then the earlier versions. However, my biggest problem is the brcmsmac driver being pushed out without power management, which appears to be taking up to 5W (5W!) of power, and never less than (3.5W). I realize it's an unrelated bug, (I've filed it here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/867869), but the kernel is averaging 9-11W for the most part - which isn't too bad.

I just suspect power management has not been a priority for Oneiric.
