The major Linux power regression situation seems to only be getting worse at this point. Following the Mobile Users Beware: Linux Has Major Power Regression and The Tests Showing Ubuntu 11.04 On A Power Consumption Binge, a variety of feedback has come in.
The fact of the matter is it's a very real problem and it's about to bite Ubuntu 11.04 and other Linux distributions planning to ship with 2.6.38 kernel or later.
There's now a stream of independent users reporting problems now that they know to look for power consumption issues with Ubuntu 11.04 and the Linux 2.6.38 kernel. To this Launchpad bug report, which is about increased power usage in Natty (11.04), there's now over a dozen people reporting to be affected by this bug. The bug report itself was started by a Canonical software engineer.
