Geting this on a 2011 Dell Lattitude, Ubuntu 11.10, always and only when the power cord has been unplugged and then plugged back in again. Once it's started happening, I can turn the kworkers on by plugging the cord in, and turn the big off by unplugging the cord. I've tried with several recent kernels including the realtime ones, and the same behaviour results.
